Module
DMSUPD (UPDATE COMMAND)
Function
CMS 'UPDATE' COMMAND -- UPDATE SOURCE FILES ACCORDING
TO SPECIFICATIONS IN UPDATE FILES. MULTIPLE UPDATES
MAY BE MADE, ACCORDING TO SPECIFICATIONS IN CONTROL
FILES WHICH DESIGNATE THE UPDATE FILES.
Attributes
DISK RESIDENT, NON-RE-ENTRANT, NON-REUSABLE
Operation
IF A SINGLE UPDATE IS TO BE PERFORMED, THEN THE INPUT
SOURCE FILE AND THE UPDATE FILE ARE OPENED. AS THE
CONTROL CARDS ARE READ FROM THE UPDATE FILE, INSERTIONS
AND DELETIONS ARE MADE TO THE SOURCE FILE, WITH THE
UPDATED VERSION WRITTEN ONTO DISK AS $FNAME.
IF MULTIPLE UPDATES ARE TO BE PERFORMED, THEN THE CONTROL
FILE IS OPENED, AND USED AS A GUIDE TO THE VARIOUS
UPDATE FILES. UPDATE FILE CONTROL CARDS MAY REFER
TO UPDATE FILES, OR TO 'AUX' FILES CONTAINING
DESIGNATIONS OF UPDATE FILEIDS. (THE EXACT FORMATS OF
THESE FILES IS DESCRIBED IN DETAIL IN THE COMMAND
LANGUAGE USER'S GUIDE.) IF NO UPDATE FILES ARE FOUND
AT ALL, A RETURN CODE OF 40 IS GENERATED (THIS CODE IS
GENERATED IN ONLY THIS WAY).
WHEN MULTIPLE UPDATES ARE BEING PERFORMED, THE INPUT
SOURCE FILE IS READ INTO STORAGE AND THE UPDATES ARE
THEN PERFORMED IN STORAGE. ALL UPDATES ARE DONE
IN STORAGE BEFORE THE OUTPUT FILE IS CREATED
ON DISK.
AS A FINAL STEP, IF THE 'REP' OPTION WAS SPECIFIED, THEN
THE $FNAME FILE IS RENAMED TO FNAME.
