--------------------------------------------------------
KINDLY REPHRASE THESE COMMENTS.
--> *01 NUM1 PIC 9 VALUE ZEROS.
--> *01 NUM2 PIC 9 VALUE ZEROS COMMENTING THIS LINE FOR TESTING
--> *01 NUM3 PIC 9 VALUE ZEROS.
--> * MULTIPLY NUM1 BY NUM4 GIVING OUTPUT-RES.
-------------------------------------------------------- |
KINDLY REPHRASE THESE COMMENTS --> indicates that there is a cobol string in the comment which might be a commented cobol code.
Althought this is day 1 for this report (means lot can be improved), I am requesting you to please suggest any other approach to this. I was going through Backus-Naur Form for cobol and was wondering if implementing that can be acheived thru cobol/rexx/any other language? |
