;VERSION 5A COMMENT
;
; THIS EDIT WAS EDITS 433 AND 452 IN VERSION 5.
;
;SYMPTOM
;
; WHEN USING FORDML IN /UNFLAGGED MODE, LOWER-CASE STRINGS
; ARE REPLACED BY UPPER-CASE STRINGS EVEN IN FORMAT AND DATA
; STATEMENTS.
;
;DIAGNOSIS
;
; WITH UNFLAGGED MODE, FORDML MUST CHECK EVERY LINE OF THE
; INPUT TEXT TO SEE IF IT TERMINATES WITH A PERIOD (.), AND
; IS THUS A DML STATEMENT. WHEN DOING SO, IT ALTERS
; LOWER-CASE INPUT ALPHABETICS TO UPPER-CASE BEFORE IT
; SCANS ITS TABLE OF LEXICAL ITEMS FOR A MATCH. AS A RESULT
; ALL LOWER-CASE ALPHABETICS ARE CHANGED TO UPPER-CASE
; BEFORE FORDML GOES ON TO BUILD ITS OUTPUT TEXTS.
;
;CURE
;
; INSTALL EDIT 542 TO GIVE FORDML AN EXTRA WORK AREA IN
; WHICH TO SAVE INPUT TEXT ASIDE AS IS WHEN IT IS WORKING IN
; UNFLAGGED MODE.
;
;WARNING
;
; IN UNFLAGGED MODE, WHEN A LINE OF DML IS SPLIT ACROSS TWO
; BUFFERS, PART OR ALL OF THE LINE MAY APPEAR IN LOWER-CASE
; IN THE OUTPUT TEXT. THIS IS BECAUSE A GREAT DEAL OF TEXT
; MAY BE INTERPOLATED IN ORDER TO CREATE THE EXTERNAL CALLS.
; AS A RESULT, THE INPUT AND OUTPUT BUFFERS ARE NOT IN SYNC
; AND TEXT WHICH WE MAY WISH TO CHANGE FROM LOWER-CASE TO
; UPPER-CASE IN THE OUTPUT BUFFER MAY HAVE ALREADY BEEN
; WRITTEN OUT TO DISK. SINCE THE ONLY TEXT IN THIS CATEGORY
; ERRONEOUSLY IS DML WHICH HAS BEEN COMMENTED OUT WITH AN
; ASTERISK (*) IN THE OUTPUT TEXT, WE FELT THAT THIS CONSTI-
; TUTED NO PROBLEM WHATEVER.

;SYMPTOM
;
; FORDML MAY NOT ACCEPT PRIVACY KEYS FOR INVOKE AND ACCESS
; STATEMENTS WHICH ARE LESS THAN FIVE CHARACTERS LONG.
;
;DIAGNOSIS
;
; THE CODE CHECKS THE ENTIRE SECOND WORD OF THE STRING ARGUMENT
; TO SEE IF THE LENGTH EXCEEDS FIVE AND SETS IT TO FIVE IF IT
; DOES. HOWEVER, THE LEFT HALF OF THE WORD IS USED TO KEEP TRACK
; OF OTHER ATTRIBUTES, SUCH AS WHETHER OR NOT THE STRING IS NUMERIC.
; THE LENGTH OF THE STRING IS STORED IN THE RIGHT HALF ONLY.
;
;CURE
;
; INSTALL EDIT 572 TO FORDML TO CAUSE ONLY THE RIGHT HALF TO BE USED.
