1. Introduction

The CHARTS utility provides the user a method to enhance thetraditional, printed output of text and viewgraph material. Two optionsare available for chart output: TEXT and VIEWgraph displays. The TEXToption provides an improvement over typical line-printer output in that a-variety of fonts may be used. The VIEW option provides an easy method toproduce standard: viewgraph output in varying colors and optionallyannotated with bullets.

Access to this utility is through the Pilot Climate Data System(PCDS).. This system provides scientific researchers with an easy method.to identify and access weather, climate, atmospheres, and oceans datasets. The: PCDS is composed of five subsystems: CATALOG, INVENTORY, DATAACCESS, DATA MANIPULATION, and GRAPHICS. The CHARTS utility is availablethrough the GRAPHICS subsystem. This User's. Guide assumes a knowledge ofthe PCDS and its user interface; however, further information andinstruction is available in Appendix A of this document and through thePCDS User's. Guide.

To utilize the features of the CHARTS facility, the user must havefirst created a file containing the desired display information with oneof the VAX standard editors.. Next, the user activates, the PCDS on theVAX (see Appendix: A), selects, the CHARTS facility, and enters, values forthe various options: which control the display of the input file.

2V CHARTS Menu

The CHARTS system allows the user to produce text and viewgraphoutput of. a-user-created input file. This menu consists of two items, asillustrated, in- Figure 2-1. Text pages will automatically be sent to thehigh resolution black and white output device (the VERSATECprinter/plotter); however,, the user may display the viewgraph pages on agraphics terminal or he may archive these pages to a file, for output viathe- PCDS GRAPHICS Subsystem- Post-Processor. The Post-Processor allowsthe combination of plots on- one page and. the specification of the mediumand size of output- See Section 2.2.3. for more details on. the use ofthis procedure.

2.1 TEXT Procedure

The TEXT procedure allows the user to output a single or multi-pagedinput file to the- VERSATEC printer/plotter. Thus, the user may improveover, the standard line-printer output by taking advantage of a variety offonts to enhance the textual display. This section discusses therequired format of the input file and the various options available toenhance the printed copy.

2.1.1 Input File Characteristics

The initial tutor display for the text input file is shown in Figure2-2. The input, file may contain several pages of textual information;all pages must be separated by a form feed character (ASCII character

12). Each page of Che text input file-must be no more than 60 lines inlength. In, addition, the text linesshould be less than 80 characters inwidth. These lines of text may contain any non-reserved printablecharacter (including blank spaces). Reserved characters include:

\ ("back slash")* (tilde)* (carat)@- ("at" sign)% (accent)_ (underscore)

Similarly, special characters, such as the tab or line feed, should notbe: used within the text file. Any blank lines of text included in thisinput file will be displayed on output to the VERSATEC printer/plotter.In addition,, the spacing as it appears- in the input file is preservedupon: output, e.g*, indentation, etc. A sample one-page text input fileis given in Figure 2-3. It should be noted that the first line is partof a title and will be centered upon output.

2.1.2 Output Specifications.

Figure 2-4- shows the tutor display of text output options and theirassociated default values. By selecting various options from the tutoredparameters described below, the user may enhance the output of thecreated input file> All selected options will affect each page includedin. this, text file. Figure' 2-5 illustrates the results of the TEXTprogram for the; input file; shown in Figure 2-3.. Here, an UNderLINedtitle of ONE. line,, a MEDIUM border, SINGLE spacing, and the CROM fontwere: specified.

Following the selection of the desired options and the completion ofthe TEXT program, the output will be directed to the black and whiteprinter/plotter for retrieval at a later time. In other words., the userwill not view the results of. the TEXT program on the terminal screen;this procedure produces hardcopy results only.

Depending upon, the size of the input file (i.e.,, the number of pagesand the number of lines, per page), the user may need a large amount offree space in his 7AX account. In addition to the size of the inputfile, the selected font style affects the size required for thegeneration of the text output. For example, the one-paged,fifty-four-lined text output shown, in Figure 2-5 required 2435 VAX blockswhen the TROM (Triplex Roman) font was specified.. However, using thesimplest font, STPL (Simple Characters), required 480 VAX blocks togenerate the output, while using the most complex font, GENG (GothicEnglish), required 2260 VAX blocks to produce the output. Followingcompletion of the printing, these large files will be deleted from theuser's VAX account. The complete set of the text outputs (and theirrespective, size requirements) generated from the input file shown inFigure 2-3 using the ten available fonts can be found in Appendix D.

The CATALOG S'ibsystea provides a user » i t h cooprehensive descriptions of aamber of cliuate paraaeter data sets and the associated sensor oeasureoentsfroa viiich the cliaate parameter! »ere derived.. These descriptions include thetenporal and spatial extents of the data sets together »ilh the experioents'data products. The catalog iuforxation is naiutaiued at t»o levels: sunuaryand detailed. Suonary intonation is stored in a data base oanaged by *coaaercial data base aanagenent systea. ORACLE. The user may obtain a l i s t ofsunnary ittforaation about the data sets by specifying keywords to Unit theinformation listed. Detailed descriptive information is oaintained in' textfiles ihicb, the user may browse is one >ould a book, using tables of contentsto locate- iu/oraatiou of interest. The information is displayed at the user'steriinal in a paged format.

The- INVENTORY Subsystaa provides detailed infomation about the teiporalcoverage and data voluoe of data sets »hicb are readily accessible througheither the PCDS or other applications stored in the ORACLE data base. The-inventory perforns t*o iaportaat functions. F i r s t , it allots a user to scanthe total data holdings and determine vbether data for a given tine period areaccessible. Second', it enables the DATA ACCESS Subsisted (described below) toautoaaticaliy locate data aeeting such user specificatiocs as tine range andparaaeters.

The DATA ACCESS Subsystea allows the user to access autoaatically the PCDSdata sets 'ising criteria such is Use range and geographic location. Outputfroai this subsystea includes user disk files or tape files in the sane forsmtas the- original data, or files in a special data-independent format ihichallors then to be input to other subsysteas of the PCDS. These special filesare called Climate Data Files (CDFs). Users nay also obtain l i s t i n g s of thedata. The data sets generated by the copy operation can be subsequentlylisted, copied or subsetted.

The; DATA SIANIPULATION Subsystea allots the user to access and aanipulate-the! data-independent files created via DATA ACCESS or by application progransvritten by users, possibly on another machine. Therefore, this subsysten isnot United only to data sets the PCDS directly supports. This subsystea'includes prograos ibich allor users to obtain a l i s t i n g of a CDF" s contents,subset a CDF. or split a gridded data set apart into its conponents (latitude,longitude, value). The output of any of these nay be input to any other DATAUANIPULATION program or the prograns in the GRAPHICS Subsystem-.

The GRAPHICS Subsystea provides the user «ith the tools to create variousgraphical representations of the data stored in CDFs. Users nay generate suchgraphical displays as histograns. "i-y" plots, contour p l o t s , and surfacediagraas. Many options exist to tailor the output for a specific need.Various color and aooochronatic display devices (e.g.. terninals and plotters)are supported. Publication/presentation quality output is also available.

Figure 2-5. Sample TEXT Output

2.1.2.1 Title

Title lines may be included in the file. The user must enter thenumber of lines (0 indicating no title) included in the input file to beconsidered a title. If multiple pages are present in this file,, thenumber of title lines applies to all pages. Blank lines may be includedin. the title. Upon output, the title line(s) will be enlarged andcentered at the top of the page;, therefore, these lines should beleft-justified is the input file (see Figure 2-3).

2.1.2*2 Underline

If a> title has been indicated, the user may request the line(s) tobe underlined. However, if no title has been specified, this parameteris ignored* Neither blank, lines nor blank spaces included in the titlewill be underlined.

2.1.2.3 Border

Each page of output may be enclosed within a border of a selectedwidth* The user may select the type of border from the following:

NONE No borderNARROW One line-widthMEDIUM Three line-widthsWIDE, Five line-widths

Illustrations of these: border widths, are given in Figure 2-6.

2.1.2.4- Spacing

The user may select the spacing of text output lines; naturally, thetype of spacing will affect the number of lines which will fit on a. pageof output. Therefore, an excess of lines because of the spacingselection may cause the upper and lower lines of the page to be "clipped"from theresulting; output (each text page is centered vertically onoutput). In other words, a full page is not continued on a seconddisplay; it is centered, thus removing the top and bottom portions of thepagev The: following options (and resulting page sizes) are available:

SINGLE Allows 64 lines per page (not includingtitle lines)

HALF One-half line-width inserted between eachline; allows 42 lines per page (notincluding title lines)

DOUBLE One full line-width inserted between eachline; allows 32 lines per page (notincluding title lines)

Samples of these spacing options are given in Figure 2-7. This figureillustrates the clipping which occurs at the upper portion of a text pagebecause of the space selection.

Figure 2-8 illustrates, these font styles. The complete character set foreach, font can be found in Appendix C.

2.2 VIEW; Procedure

The VIEW, procedure allows the user to output a single or multi-pagedinput: file in viewgraph format^ The initial tutor display for the VIEWproc is. given, in. Figure- 2-9. Here,, the user must enter the input filename- and desired output device, i.e., the output may be directed, to theviewing, terminal and/or to, a plot file for later display by the-, PCDS'.GRAPHICS: Subsystem Post-Processor (see Section 2.2.3). If the viewgraphsâre; to be' displayed on the terminal, the procedure will pause followingthe- graph of each page contained in the- input file. In, order to view,subsequent pages, the user should enter a carriage return.. This sectiondiscusses, the required format of the input file and the various optionsavailable to enhance the display of the viewgraph pages.

2.2.1 Input File Characteristics

The input file may contain, several pages of information; all pagemust be separated by a form feed character (ASCII character 12). Eachpage must be no more than 40 lines (including blank lines) in length; theviewgraph lines should be: less, than 80 characters in width. However, onoutput all lines will be wrapped, (at word breaks) after 50 characters inwidth.. The- lines; of the viewgraph may contain any non-reserved printablecharacter (including blank spaces). Reserved characters include:

\ ("back slash")- (tilde)*" (carat)@ ("at" sign)> (accent)_ (underscore)

Similarly, special characters, such as the tab or line feed, should notbe used within the viewgraph file. Any blank lines included in thisinput file will be displayed on output. A sample two-page input file isgiven in Figure 2-10. The first three lines of each page are part of atitle and will be centered upon output.

2.2.2 Output Specifications

Figure 2-11 shows the first tutor display of viewgraph outputoptions and their associated default values. By selecting variousoptions, from the tutor parameters described below, the user may enhancethe output of the created input file. All selected, options will affecteach, page included in this viewgraph file. Figure 2-12 shows the resultsof the VIEW proc for the sample input file in Figure 2-10. Here,BULLETS,, a TITLE of THREE lines, a NARROW border, HALF spacing, LEFTjustification, and CROM font style were specified.

Following the initial viewing, theuser may find it necessary tomodify and then repeat the display of the input file. Therefore, it issuggested that the user first view the contents of the input file with alimited number of options, (e.g., no border, STFL font, etc.) and ifnecessary, enter TAB COMMAND mode, edit the input file to achieve thedesired results, and repeat the procedure.

2.2.2.1 Color

The user may select colors for various regions of the viewgraphpage. These areas, the main body,, the title line(s), and the border maybe output in different colors. However, if the output is, directed to ablack and white device,, the color selection has no effect upon theviewgraph display. The following list details the color definitions:

0. Default device color1. Black:2» Red3. Green4.. Yellow (Brown on the HP plotting device)5. Blue6. Magenta (Violet on the HP plotting device)7.. Cyan (Orange on the HP plotting device)8.. Waite

If titleline(s:) and/or a border is selected, the colors for theseregions are entered through subsequent tutor displays..

2.2.2.2 Bullets.

The- user may optionally specify that "bullets" are to precedenon-title lines in the viewgraph. output. If selected, all non-title,non-blank lines of all pages of output will be annotated with bullets(see Figure 2-12).

2.2.2.3 Title

Title lines-may be included in the file. If multiple pages arepresent in the input file:,, the number of title lines applies to allpages. Blank lines may be included in the title. Upon output, the titleline(s) will be enlarged and centered on the page; therefore, these linesshould be left-justified in the input file (see Figure 2-10). If a titleis indicated, the user will view the tutor display shown in Figure 2-13 .

Here, the user may enter the number of lines to be considered a title aswell as. the color of these lines. Optionally, the user may request thetitle line(3) to be-underlined. Neither blank title lines nor blankspaces will be underlined.

2.2.2.4 Border

Each page of output may be enclosed within a border of selectedwidth. The user, may select the type of border from the following:

NONE No borderNARROW One line-widthMEDIUM Three line-widths.WIDE Five line-widths

See Figure 2-6 for samples of these border width options. If a border isselected, the user will view the tutor display shown in Figure 2-14 toselect a color for the- border.

2.2.2.5 Spacing,

The user may select the spacing of viewgraph output lines;,naturally,, the type- of spacing will affect: the number of lines which willfit on a page of output. Therefore, an excess of lines because of thespacing; selection may cause the- upper and lower lines of the page to be"clipped"* from theresulting, output (each viewgraph page is- centeredvertically on output). In. other words, a full- page- isnot continued on asecond, display;: it is centered thus removing, the top and bottom portions:.The following, options, (and resulting page sizes) are1 available:

SINGLE Allows 40 lines per page (not includingtitle lines)

HALF' One-half- line-width1 inserted between eachline;, allows. 27 lines per page (notincluding, title lines)

DOUBLE. One. full line-width inserted between eachline; allows. 20 lines- per page (notincluding title lines)

Figure. 2-15 shows the effects of the spacing selections on a particularviewgraph input file.

2.2.2.7 Font Style

The user nay specify one of several font styles. The title line(s)and the body of all pages of viawgraph output will be drawn in thespecified font. The following fonts are available:

STFL Simple charactersSROM Simplex Roman fontDROM Duplex Roman fontCROM Complex Roman fontTROM Triplex Roman fontCITA Complex Italic fontTITA Triplex Italic fontSSCR Simplex Script fontCSCR Complex Script fontGENG Gothic English font

See Figure- 2-8 for samples of the various font styles. The completecharacter set for each font can be found in Appendix C.

2.2.2.8 Hardcopy

If a hardcopy device is connected to the current display terminal,all screen output may be printed by specifying "YES" to the HARDCOPYoption. Alternatively, the user may enter a plot file name to archivethe results- for display by the PCDS GRAPHICS Subsystem Post-Processor. Amore detailed description of the Post-Processor procedure is presented inthe next section.

2.2.3; Hardcopy Output

The GRAPHICS Post-Processor provides the user a means forredisplaying plots generated by the CHARTS utility that have been savedin a plot file (i.e., TERMINAL was set to a file name in the first VIEWtutor or HARDCOPY was set to a file name in the second VIEW tutor). ThePost-Processor allows the user to specify the input file and the outputdevice. The output may be a terminal,. the black and whiteprinter/plotter (VERSATEC), the color HP plotting device, or a tape forlater slide production. A device for creating color viewgraphs directlyon transparencies will be available in the future. For specific hardcopydevices, the user will be prompted for such items as output medium, size,etc.. Figure 2-16 illustrates the first tutor display for thePost-Processor.

Each "printed" display may consist of one to four plots on a singlepage. Therefore, if several viewgraph pages, are included in the plotfile, the user may place up to four on one plot display. However, if onepage per plot is desired, the user must run the Post-Processor procedurefor each page. When two plots are selected, the layout may be splitvertically or horizontally. The second tutor display for thePost-Processor is shown in Figure 2-17. Here, the user may enter whichplot(s) are to be included in the display. For example, if the fourthplot in the input file is to be the only plot on the display, the userenters PLOTNO(1)=4, i.e., the first plot, here, the only one, is to be

the fourth plot found in the input file. As previously stated,subsequent tutor displays may appear for specific hardware options.

3. Reserved Characters

Several reserved characters may be used within lines of a text orviewgraph input file. These characters change the display of allsubsequent line elements until the end of the input line or anotherreserved character is encountered. These reserved characters and theirfunctions- are as follows:

@' ("at" sign) Font change character.

"" (tilde) Superscript character.

_ (underscore) Subscript character.

J.I Font Style Character

In both the- TEXT and VIEW options, the user may specify a font stylewhich will apply to all lines, of all pages, of the generated output.However, it is often desirable to change the character style within atext in order to emphasize a word or sentence or to insert a specialsymbol or mathematical character. This alteration of font can beaccomplished by inserting, the^ "Font Escape- Character" followed by thefull four-letter font name. Any of the previously mentioned fonts (seeSection 2.1.2.5 or 2.2.2.7) may be used here. In addition, many specialcharacters, may be included in the display by using one of the following,fonts:

SGRE Simplex Greek FontCGRE Complex Greek. FontGGER Gothic German FontGITA Gothic Italic FontCCYR Complex Cyrillic FontLMAT Lowercase Mathematics FontUMAr Uppercase Mathematics, FontASTR Astrology FontMETE Meterological FontMUSI Music FontSYHB Symbols. Font

The complete character set. for each font can be found in Appendix C..

In order to change the font within a line of text, the user mustinsert an "@" sign followed by the four-letter font name. All charactersfollowing this string and contained on the input line will be displayed,in the named font; however, the character style will return to thepre-set font on all subsequent lines. If a font string, is inserted andthe user wishes to return to the pre-set font (or display a second fontstyle) prior to the end of the line, an "@" sign followed by the pre-setfont name (or alternate font name) must follow the last character to beoutput in the alternate font. It should also be noted that the font name

25

must be in Che same case as the last alphabetic character preceding the"@" sign (all input lines are cycled through a procedure where changes incase are marked).

The viewgraph input file shown in Figure 3-1 illustrates the use ofthis font-change process; the output from this file is given in Figure3-2.. Here, the font style was altered from the pre-set Triplex Roman(TROM) font in order to italicize words and take advantage of severalspecial symbols. For example, the phrase "Taylor Expansion" is precededby the string "@tita" and succeeded by the string "Strom". Upon output,this phrase is placed in the Triplex Italic font and the remainder of theline is returned to the Triplex Roman font (i.e., the pre-set fontstyle). The. final line of the input file illustrates the use of theLowercase: Mathematical Font (Imat) in order to display a specialcharacter. This character is alphanumerically represented by a "?" andwill be displayed as an inequality sign (see Appendix C). To output allsubsequent characters in the pre-set font, the string "@trom" is insertedfollowing this special character. In both of these examples, the fontname following the "(§" sign is in lowercase letters since the precedingalphabetic character is also in this case.

3.2 Subscript and Superscript Character

The user may subscript or superscript characters by the insertion ofa reserved character. The Subscript Escape Character is the "_"(underscore); the Superscript Escape Character is the "~" (tilde). Eachoccurrence of the subscript character will lower the position ofsucceeding characters approximately one-third of the line-height;similarly each occurrence of the superscript character will raise theposition of succeeding characters approximately one-third of theline-height^ When the end of a line is reached, the scripting level isreturned to the zero position. If a subscript is inserted and Che userwishes to return to the normal position prior Co Che end of Che line,, asuperscript character must follow the last character to be subscripted.Likewise, a subscript character must follow the last character to besuperscripted.

The viewgraph. input file- shown in Figure 3-1 illustrates the use ofthis subscripting and superscripting process in order Co output severalmathematical expressions; the output from this file is given in Figure3-2. In the first formula, the superscript character is used Co indicateexponentiation. Following the completion of the line, the scriptinglevel, is returned to the zero position. Alternatively, in the inputphrase "r_n~(x)", the "_" causes the character "n" to be subscripted; the"""" following this "n" causes Che remainder of Che inpuc line to recurnCo the zero position.

Appendix A — use of the PCDS

Use of the PCDS

A.I General Information

This appendix provides brief direction in the use of the PilotClimate Data System (PCDS). For more detailed instruction, the user isdirected to consult the PCDS User's Guide.

The user interface of the PCDS is. the Transportable ApplicationsExecutive (TAE). This system provides, menu selection displays, tutor(option selection) displays, and on-line help information. TAE providesthe inexperienced user an easy method to select the appropriate programs.and the required input for these programs. Alternatively, TAEfacilitates, program access, for the experienced user.

In order to access the PCDS, the user must have a user ID andpassword for this VAX 11/780 computer system- The log-on, procedure is asfollows:

<R£TURN>

Username; uname <RETURN>Password:, pword <RETURN> (the password will not be displayed)

(Computer Messages)

Following the- successful sign-on, to the computer,, the user must activatethe PCDS software system by entering the following command:

$: (3PCDSTJSER: START

Following activation of the PCDS, the user may be- required, to enter thetype of terminal he- is currently using. This is required for any remoteterminal not directly connected to the VAX. The user will then view PCDSsystem messages. A carriage return following this. PCDS banner willadvance the user to the initial (or root) menu (see Figure A-l)..

A..2 Use of TAE

A. 2.1 General

TAE provides a consistent interface to all programs and programinputs in the PCDS. TAE utilizes menus for program selection,, tutordisplays for specifying inputs to these programs, a command mode forprogram selection by experienced users, and help features. This sectionprovides basic instruction in the use of the TAE menu, tutor, command,and help functions. For more detailed information, the user shouldconsult the TAE Primer and/or the TAE User's Guide.

TAE displays (e.g., Menu, Tutor, and Help screens) follow severalconventions. First, multiple pages of information are indicated by a "+"following the page number on the first line of the display. Second,valid entries to be typed following the "?" prompt are listed on the lineproceeding the prompt line. Third, command and parameter names may beabbreviated with the first several characters which uniquely identify thedesignator (e.g., EX for EXIT, R for RUN, M for MENU, etc.)..

A.2.2 Help Mode

TAE provides help.information on itself as well as on individualprocedures and their required inputs. The available help options, are asfollows:

<RETURNX Move to the next page of the helpdisplay. The first page will be the"next" page after the last page.

PAGE n Display page number "n".

EXIT Exit the help display and return tomenu or tutor mode.

For example, when a menu is displayed, the user may enter "HELP"following, the: "?" prompt. The resulting information aids the: user in. TAEfunctions . Alternatively,, to receive instruction on a particular -menuitem,, the user may enter "HELP n" where "n." is the number in question.

A.2.3 Menu. Mode

-Following a successful access of the PCDS, the user will view theinitial (or root) menu of the PCDS system (see Figure A-l). A list ofvalid command entries followed by a prompt line is located at the bottomof. the menu mode screen. The user may enter one of these commandsfollowing the "?" prompt. The available prompt-line options are asfollows:

HELP- Display information on the operationof TAE.

HELP * Display information on the currentmenu.

HELP n Display information on entry "n" ofthe current menu.

HELP proc Display information on the namedprogram (following the menu item andin parentheses or brackets).

BACK Return to the previous menu.

TOP Return to root (first) menu.

A-5

MENU menuname Activate menu "menuname". If no menuname- is given, the current menu isredisplayed. The menu name is shownto the right of the initial menudisplay line.

COMMAND Exit the MENU mode and prompt for aTAE Command Language (TCL) command.

LOGOFF Log the user off the system.

To access one of the PCDS Subsystems, the user should now enter a number,one through five. The user will eventually access a program (or "proc"in TAE terminology) by making successive selections through menus.

A.2.4 Tutor Mode

After the user has successfully accessed a "proc", a "Tutor Display"will appear. This tutor display allows the user to enter inputparameters which the program requires. Initially, the screen shows theparameter name, description, and default value. Many of these parametershave default values. As the user selects values for these options, thetutor screen will be updated. In most cases, the entries made will bevalidated. A list of valid command entries followed by a prompt line islocated at the: bottom of the tutor screen. The user may enter one ofthese commands following the "?" prompt. The available prompt-lineoptions are as follows:

<RETURN> Display the next page of the tutordisplay.

parmavalue Assign a. new value to the option named"parm".

HELP Display help information on. TAE tutoroperation.

mETLP * Display text describing the currentprogram.

HELP parm' Display detailed text describing theoption "parm".

PAGE n Display page "n" of the tutor display.

PAGE parm Display the page containing the option"parm".

SHOW parm. Display the value entered for theoption "parm".

RUN Execute the program with the selectedoptions.

A-6

EXIT Terminate the tutor session withoutrunning, the program.

SAVE filename Save the current option values in afile named "filename".

RESTORE filename Restores the option values from thefile named "filename"'.

RESTORE LAST Restore the option values from themost, recent tutor RUN..

For example,, valid entries for the input parameters may be obtained byentering "HELP" followed by the parameter name. Once the value for aparticular parameter is selected, it may be entered by typing."PARM-VALUE", where PARM is the option name and VALUE is the selectedinput., The screen will automatically be updated with this entry. Whenall entries have been made, the user should enter "RUN" (or "R") to runthe program with these values. Depending upon the program, the user mayview a prompt line (e.g., "PCDS-VIEWOPT>") indicating that additionaltutor displays are available. In order to display these tutors on thescreen, the user should enter "TUTOR".

A.2.5 Command Mode

Command mode is. a method for an experienced user to gain Immediateaccess to a particular program, (proc). The user accesses command mode by"entering "COMMAND" while in menu mode. A prompt of "PCDS>" will appear.One: of the following; commands may now be entered:

DCL Access; the VAX from TAE; a "$_" promptappears - To return to command mode,enter "TAE"..

EXIT Terminates the TAE session and remainsconnected to the VAX account (i.e., a."$" prompt appears).

HELP" Display information on the operationof TAE. in command mode.

HELP command Display information, on the namedcommand.

LOGOFF Terminate' TAE. and log the user off thesystem.

MENU. Display the current, menu.

TUTOR Display the current tutor screen.

procname Run the program named "procname".

A-7

Thus, by entering a proc name in command mode, an experienced user mayrun programs without accessing a menu first. If input parameters arerequired by the program, the user must follow "procname" with"parm value". Alternatively, the user may enter the proc name only; amessage will be displayed indicating input values are required. The usermay then enter "TUTOR" to view the tutor display.

When the DCL command is entered, any valid VAX command may followthe "$_" prompt. For example, in the VIEW procedure, the user may needto modify an input file. Therefore, the user may enter "DCL" and invokeone of the VAX editors. After all modifications have been made, the userre-enters TAE and runs the VIEW program again. This process may berepeated until a satisfactory viewgraph display is attained.

A.3 PCDS GRAPHICS Subsystem

As shown in Figure A-2, the CHARTS facility is part of the GRAPHICSSubsystem. Therefore, the user should enter "5" in the root menu displayto access the GRAPHICS Subsystem. The GRAPHICS menu, Figure A-3, willnow appear. The CHART utility may be used by entering a "3". If a plotfile has been created, the Post-Processor may then be accessed throughmenu item 4.

Appendix B — Sample GHAUTS Sceoario

Sample CHARTS Scenario

This appendix illustrates a typical user scenario of the PCDS CHARTSutility. In this scenario, the user accesses the Pilot Climate DataSystem and locates the CHARTS utility. The user first- runs the TEXTprocedure to print a specified input file. Next the user activates theVIEW process and graphically displays the specified input file. Thisfile is then modified and the VIEW procedure is run. a second time. Theresulting, hardcopy file is then used in the GRAPHICS SubsystemPost-Processor.

In the sample scenario, the left section of each page depicts thescreen displays the user will view; the right section providesexplanatory notes. A typical screen display consists of a screen or pageof input values- and one. line at the bottom of the page for the userresponse. In the sample case, the user inputs are shown on this line.In some instances, one screen display will require several responses fromthe user. The user will enter these values one at a time. The screen isthen, updated with the value; however, in this scenario, all requiredresponses will be shown on separate lines- of a single screen. Inaddition,, all user responses are terminated with a carriage return(<RETURN>),. though: the' <RETURN> is not explicitly shown in the scenariodisplays;.

This scenario- is intended to assist a new user in becoming familiarwith the: CHARTS utility.. However, it does not illustrate all capabilitesof the facility.. The user may obtain additional aid in running thesystem1: by utilizing the online HELP facility.

Sample TEXT Output

This appendix illustrates, the various font styles for the sampleTEXT input file of Figure 2-3. The displays have been reduced slightlyfor inclusion in this document. In all cases, an UNderLINed title of ONEline, a MEDIUM border, and SINGLE spacing were specified; only the fontselection was varied. In addition, the size required for the generationof the output is shown beneath the display.

SYSTEM QVERVIEVThe PCOS consists of five subsystems: CflTflLOG, INVENTORY, OflTfl PCCESS,

OflTfl MfiNlPULflTION,. and GRAPHICS, fl brief description of aach of the fivesubsystems of the PCDS is provided below.

The CRTflLOG Subsystem provides a user with comprehensive descriptions of anumber of cl imate- parameter data sets and-the associated sensor measurementsfrom which the climate parameters vere derived. These descriptions include thetemporal and. spatial extents of the data sets together w-ith the experiments'data, products. The catalog information is ma-intained at two levels: summaryand detailed. Summary information is stored in a data base managed by acommercial data base management system, ORRCLE. The user may obtain a l i s t ofsummary information about the datasets by specifying keywords to l i m i t theinformation listed-. Oeta-iled descriptive information is mainta.inecr in textfiles, which the user may browse- as one would a book, using tables of contentsto locate- information of interest. The information is displayed at the user'sterminal in a paged format.

The INVENTORY Subsystem provides detailed information about the temporalcoverage and data-vo.lume of data sets which are readily accessible througheither the PCDS or other applications stored in the ORflCLE data base. Theinventory performs two important functions. First, it allows a user to scanthe' total data holdings and determine whether data for a given time period arraccessible. Second,, it enables the DflTfl flCCESS Subsystem (described below) toautomatically locate data, meet ing such user specifications as time range andparameters.

The - OflTfl flCCESS Subsystem allows the user to access automatically the ?CDSdata sets using criteria- such as time range and geographic location. Outputfrom this, subsystem includes user disk files'or tape f i l e s in the same formatas- the' origina-l data,, or files- in a special data-independent format whichallows them to be input, to other subsystems of the PCDS. These specia-l f i l e sare called: Cl i mate Data- Fi les iCDFs). Users may also obtain l i s t i n g s of '.hedata-. The data-sets generated: by the copy operation can be- subsequentlylisted, copied or subsetted.

The OR-Tfl MRNIPULflTION Subsystem allows the user to access and manipulatethe data-independent f i l e s created via OflTfl flCCESS or by application programswritten by users., possibly on another machine. Therefore, this subsystem isnot l i m i t e d only to data sets the PCDS directly supports. This subsystemincludes: programs which allow, users to obtain a I isting of a CQF's contents,subset a CDF, or s p l i t a-gridded data set apart into its components ( l a t i t u d e ,longitude, value). The output of any of these may be input to any other DPT.Q-MflNIPULATIQN program or the- programs in the GRRPHICS Subsystem.

The GRAPHICS Subsystem provides the user with the- tools to create variousgraphical representations of the data- stored in CDFs. Users may generate suchgraphical displays as- histograms, 'x-y' plots, contour plots, and surfacediagrams. Many options exist to t a i l o r the output for 3 specific need.Various color and monochromatic d i s p l a y devices (e.g., terminals and plotter?)are1 supported. Publication/presentation quality output is also a v a i l a b l e .

The CATALOG' Subsystem provides a user with comprehensive descriptions of anumber of- cl imate parameter data sets and the associated sensor measurementsfrom which the climate-parameters were derived. These descriptions include thetemporal and spatial extents of the data sets together w i t h the experiments'data products. The catalog information is maintained at two l e v e l s : summaryand detailed. Summary information is stored in a data base managed by acommercial data base- management system, ORACLE. The user may obtain a l i s t ofsummary information about the data sets by specifying keywords to l i m i t theinformation listed. Detailed d e s c r i p t i v e information is maintained in t e x tf i l e s which- the-user may browse as one would-a book, using tables of contentsto locate- information of interest. The information is displayed at the user'sterminal in a: paged format.

The- INVENTORY Subsystem provides detailed information about the temporalcoverage- and. data volume of- data' sets which are rea d i l y accessible througheither the PCOS: or other applications s.tored in the ORACLE data base. Theinventory performs: two important functions. F i r s t , it a l l o w s a user to scanthe- total data, holdings, and determine whether data for a given time period oreaccessible. Second, it enables the DATA ACCESS Subsystem (described below) toautomatically- locate data meet ing. such user specifications as time range andparameters.

The- DATA, ACCESS. Subsystem a l l o w s the user to access automatically the PCD3data.-s.ets using, cri teria- such as time range and. geographic location. Outputfrom this subsystem includes user d i s k f i l e s or tape- f i l e s , in the- same formata.s- the orig-inal data., or f i l e s in a special data-independent, format -*hichallots-, them- to be- input to other subsystems of the PCDS. These special- f i l e sare caMed-Cl imate Data Files. (CDFs). Users may. also obtain l i s t i n g s of the-data. The data: sets generated, by the copy operation can be subsequentlylisted,, copied or subsetted.

The.'DATA MANIPULATION Subsystem a l l o w s the user to access and manipulatethe'data-independent f i les created- v ia O'ATA-. ACCESS or.by application programswritten by users, possib l y on another machine. Therefore, t h i s subsystem isnot l i m i t e d - o n l y to datasets- the- PCDS directly supports. This subsystemincludes programs- which allow, users to obtain a l i s t i n g of a COF' s contents,subset a CDF, or s p l i t a gridded data set apart into its components ( l a t i t u d e ,longitude, value). The- output of any of these may be input to any other DATAMANIPULATION-program or the programs in the GRAPHICS Subsystem.

The GRAPHICS Subsystem provides the user w i t h the tools to create variousgraphical representations- of the data, stored in CDFs. Users may generate suchgraphical d i s p l a y s as histograms, "x-y" p l o t s , contour p l o t s , and surfacediagrams.

These special filesare called Climate- Data Files (CDFs). Users nay also obtain listings of thedata. The data sets generated by the copy operation can be subsequentlylisted, copied: or subset ted.

The DATA MANIPULATION Subsystem allows the user to access and manipulatethe data-independent files created via DATA ACCESS or by application programswritten by users, possibly on. another machine. Therefore, this subsystem isnot Limited only 'to data sets the PCDS directly supports. This subsystemincludes programs fhich allow users to obtain a listing of a CDF's contents,subset a CDF, or split a gridded data set apart into its components (latitude,longitude', value). The output of any of these may be input to any other DATAMANIPULATION program or the programs in the GRAPHICS Subsystem.

The GRAPHICS. Subsystem provides the user w i t h the tools to create variousgraphical representations of the data stored in CDFs. Users may generate suchgraphical displays as histograms, "r-y" plots, contour plots, and surfacediagrams. Many options exist to tailor the output for a specific need.Various color and monochromatic display devices (e.g.. terminals and plotters)are- supported. Publication/presentation quality output is also available.

These descriptions include thetemporal and spatial extents of the data sets together aith the experiments'data products. The catalog information is maintained at two levels: susaaryand detailed. Summary information is stored in a data base managed by <icommercial data base management system, ORACLE. The user may obtain a list ofsummary information about the data .sets by specifying keywords to limit theinformation listed. Detailed descriptive information is maintained in textfiles yhich the user may browse as one aould a: book, using tables of contentsto locate information of interest. The information is displayed at the user'sterminal in- a. paged format.

The rHVSXTQRY Subsystem, provides detailed information about the temporalcoverage and data, volume of data sets ahich are readily accessible througheither the PCOS or other applications stored in the ORACLS data base. Theinventory performs tvo important functions. First, it allots a user to srunthe total data, holdings and determine' ahether data for a given time period areaccessible: Second, it enables the SATA ACCESS Subsystem (described belo>a) toautomatically locate data meeting such user specifications as tine range andparameters.

The OATA;ACCESS Subsystem allovs the user to access automatically the PCDSdata sets, using criteria such as time range and geographic location. Outputfrom this subsystem includes user disk files or tape files in the same formatas the original data-, or files in a special data-independent format whichallovs them to be input to^ other subsystems- of the PCDS. These special filesare: called- Climate' Data files (COFs). Users, may also obtain listings of thedata.
