LINORD calla LINTYP to c1anify each U.na in the

&ourc. deck. If tha line ia completely blaak or 18 blank except for a zero in column 6. LINORD will de­

lete the line and call ERRMSG to write the error mes­

sage, "Blank line delated". If :ile line is unrecog­

nizable it viII also be deleted with an er~or message

written. All of the acce~ted lines are counted and

written onto a scratch file. NFl (FSET3). The ter­

minal line (with letter T in column 1) signals the

end of input. It will not be transferred to NFl.

If the line prec.cing the terminal line h DOt an

mm line, Ln,OlIJ) will inaert an END line and count

it. LINTYP will substitute a + for = in column 6 of a continuation line.

In sddition to checking the type of line, LLNORD

checks U lines are in the right order. If an END

line is followed by any kind of line other than an

initial or terminal line, the linEI will be deleted

In this atage a statement may be flagged or changed.

SJIII8times, the change requires the insertion of extra contin_tion linu or a new stataent. There are

four kinds of statements in which nonstandard usages

well be changed, DATA, FORHAT, two-branch logical IF,

and Hollerith replacement stataMnt8. In a DATA

.tatlllmlt. 1£ the list of <:onstanta contains a

Hollerith constmlt of the form nL •••• the letter

H will replace the letter L, resulting in DB .•. In a FORHAT scatement, a comma will be inserted

if it was omitted following either a Hollerith or

apacing (aX) sp8c1ficat10n, while a comma preceding

o~ followiQg a slash will be deleted. An 8sterisk­

encl03ed Hollerith specification will be replaced

by an DR ... specification. A parenthetical group

with"ut e repeat count ~"ill be changed in Oile of

two ways. If the group is followed by a format

specification, the number 1 is inserted as a rl~peat

count. If the group terminates the FORMAT state­

ment. the number 60000 is inserted as a repeat counc

and a sln~b i8 inserted before the group·s final

dght parenthesis. A two-branch logical If such

as IF ( ••• } nl ,n2 will be changed to the two

statements

IF ( ••• ) GOTO ~

COTO n2

A Holler~th replacement statement of the form

var~able - DR .•• or variable - tiL •••

will be replaced by the two statements

DATA dummy I DB ••• I

variable ~ dummy

The dummy name is either IIIIdd (for integer type)

or HHBHdd (for real type) where d is a decimal

digit.

With the exception of che unlimited repeat count

correction in a FORMAT statement, DOne of these

changes will be explained in an error message. How­

ever, the final version of the statement will be

flagged "CHANGED" or "INSERTED".

The flags, which are written on NF2 along with

the first line of the final statement but beyond

column 80, point out whether it is "NOT ANSI",

"INCOMPLETE", "POSSIBLY NOT ANSI", "CHANGED", or

"INSERTED". The headline of each routine is identi­

fied by the flag "NEW PROC". If the statement passes

all the tests it is written on NF2 without flags.

All of the statement-checking routines write

explanatory error messages on the output file if a

nonstandard usage is detected. If an unspecified

repeat count is detected in a FORMAT statement. the

statement will be changed on NF2 and the changes

will be described on the output file. All of the

5

error mesaages start by :1dentifyiDg the line or

statement in which the error was detected. The rest

of the messsge tells what was wrong. The possible

explanatlol18 are listed in Table I. along with the

names of the routines calling for ther .•

At the end of the second stage, the final ver­

sion print flle, NF2. is vritten on the output f11e.

NFl is rewound and the finsl version SO-column card

images are written on it.

All of the routines in ANSIFT are listed and
