A new Biweekly Report form for KPSCCM programmers has been d i s ­tributed. This form includes spaces for reporting percent of progress on various phases of a program, as well as for discussing the problems en­countered and progress made.

Further detai l s on the KPSCOM programs can be found below.

(R. P. Mayer)

Single Track Tracking Program! 8500

The new version of the tracking program has been run with data. There i s a major bug in the program in that a l l of the data i s concentrated at about 5 points on the scope and at this time I am trying to determine what causes the error in the radar display. I t appears to be in the con­version routine. Another bug i s the inability to in i t i a t e on any of the radar data.

(W. M. Oramling)

Height-Finder Flight and Equipment Test Program; 8209 4 8102

The Height-Finder Flight program is considered to be complete to the point where It should be combined with the tracking program. A deck of octal corrections was used to simulate, as far as possible, the Input to the Flight Test program. All print-outs have been checked and a l l varia­tions in program logic have been tested as far as possible .

The Height-Finder Equipment Test program has been operating to the requirements of the test team. A few changes have been made and some trouble has been localized to card processing errors.

The documentation i s In process for both programs, being in to ta l about Ojt complete.

(J. J. Maroney and F. J. Sweeney)

Quick Radar Recapitulation Program: 3225

About 70jt of the coding has been done and about 2/3 of that .d.11 be sent to the card room this week.

(Helen E. Quirk)

LRI OFI Pattern Check Program; 8201

This program i s complete except for the conversion to SA0E and to the FST-1 pattern. A new assembly wi l l be made and checked out before attempting to convert the progra-. for the FST-1 pattern. This assembly contains a l l known aodificaUcns requested for this program.

Pattern Punch Generator; 802501

The pattern punch program has been checked out and i s operating correctly. A few minor corrections w i l l be necessary before i t can be com­bined with another completed program. The combination w i l l provide the means to punch radar data cards and make insertions by using the A and B toggle switch registers . Because of conflicting tags in the two programs, more changes w i l l be necessary before a combined compilation of the two programs can be made. For checking out purposes, we'are using the program to be integrated as a subroutine.

(Joseph A. Palermo and Glenn F. Paulsen Jr . )

Pattern Card Conversion Program! 801702

The routine to convert the LRI data has been successfully com­pleted. The routine to convert the GFI data needs more refining.

(C. Toohig and B. Awad)

Pattern Check Tape Printout: 8024. 8S10. 8S60

An error was found In the Pattern Check Program which made th i s program inoperative. The error has been fixed and this program has been modified to handle any similar s i tuat ions . Three subroutines have been added, bringing the program from i t s original form of 158 cards to i t s present (mod. 09) form of 239 cards. These extensive modifications and additions have necessitated revision of a l l flow diagrams previously drawn.

(David L. Greenhalgh)

LRI Single Message Test; 8903

The cards wi l l be finished (from the card room) this Wednesday (20 June) and I expect to run the program on the computer for the f i r s t tine this Friday. All research for the program has been completed. Con­version to the SAGE version of this program has been considered through­out the coding and could easily be fac i l i ta ted by octal correction cards for changing a few minor Instructions. This program should be completely finished by 9 July 1956.

(D. T. O'Neill)

I am now coding the print out procedure.

(Marilyn R. Lynch)

Manual foput keyboard legt i 85QJ.

Coding for the operational part of the oMogram is about 25$ com­plete, and should be finished around the 20th cd£\pe. Console E-21 was tested on 12 June and the results Indlcated^t^Sp^ogram was operating s a t i s ­factori ly . As each row of the console we^e^sted. an indication of "good" onsole wag tr

or "bad" was shown on the DD together with the row number and console be­ing t e s t e d .

Consoles present ly Ins ta l led in SSS are not in t h e i r f inal ized form. The program wil l be wr i t ten to t e s t BSS keyboards as they w i l l be and not as they are a t present , to avoid constant modifications as t h e consoles are brought up to d a t e .

(John T. Tadler)

The computer t e s t proved t ha t the program methods generated w i l l work s a t i s f a c t o r i l y . There now remains the job of modifying th i s program to include not only one console and i t s associated ED & SD, but 105 con­soles and as many CD's. This modification has progressed s a t i s f a c t o r i l y and I t i s expected to be ready for compilation by Wednesday 20 June.

(Wilmot H. Hansen)

C r o s s f 11 Test Program; 81,0400

The tes t team i s current ly s a t i s f i ed with 810400, as modified by a l a rge number of oc ta l correct ion cards .

The program w i l l be documented in i t s present form; oc ta l cor­r ec t ions w i l l not be incorporated in to a re-assembly. (810400 makes use of the old assembly program)

The deadline for documentation i s mid-July. The requirement for extensive detailed flow char ts could ser iously upset meeting the deadline.

(L. J . Rose)

Teletype Message Teatt 8011

Continued operation of this program through use of the checker has revealed errcrs both in this program and In the checker. Considerable progress has been made, however. Conversion of the card data from Hollerith to teletype code stored on the A.M. drums is now successful.

(Oeorge C. Cox)

Qround/Oround Message DispUiTt 810306

Documentation of t h i s program i s the l a s t major thing to do. During the l a s t week, p i c tu res were taken for this document on the SD camera console. A few flow diagrams have been typed. These flow diagrams are based on Wes Marston's method. A rough draf t has been w r i t t e n , which Chris Sherrerd has looked over . This document does not describe the flow diagrams, so i t must be modified or an addit ion must be added to describe the flow diagram.

Square Root Subroutine: 801204

An overflow has been detected. Correction of the program wi l l involve the changing of some constants.

The dual precision subroutines (except for division) are com­pleted and checked out. The memo i s written but may require changes in the division appendix. Division i s almost done except for a few de ta i l s . We ran the conversion program and expect to start debugging.
