What is the difference between RETURN CODE & MAXCC CODE?
oldman

Actually a step may have both return codes and MAXCC. Example 1: You have an IDCAMS step that deletes multiple VSAM files. Each delete statement will produce a return code, and the MAXCC for that step...

A RETURN_CODE shows the status of each step within a job and the maximum RETURN_CODE is 256, where as MAXCC shows the end of the programme status, if the MAXCC is ZERO it means that job is executed successfully. We have MAXCC are like 0,2,4,8. MAXCC=8 means fatal error.

01 WS-VAR USAGE IS INDEX.it is a valid working storage definition. We can use this variable to store displacement value of another table index. Like normal table index it cannot be used in any computataions and terminal control statements.Thanks,Narender

What is an in line PERFORM? When would you use it? Anything else to say about it?
The PERFORM and END-PERFORM statements bracket all COBOL II statements between them. The COBOL equivalent is to PERFORM or PERFORM THRU a paragraph. In line PERFORMs work as long as there are no internal GO TOs, not even to an exit. The in line PERFORM for readability should not exceed a page length - often it will reference other PERFORM paragraphs.

What is the logical difference between Move A TO B and COMPUTE B = A?
prasenjit_in
- Sep 1st, 2008
Move replaces values one by one, depending on the data type move is from left-right/right-left.Compute on the other hand completely deletes the previous value in the variable and writes the new value to.

thequestsailor
- Jun 25th, 2007
The answer is a. 27in the first if else statement the condition fulfills and it will move 57 to C and then gradually going to the 2nd loop the condition again fulfills and then it will replace the previously stored 57 and replace it by 27 as per the condition of the 2nd loop.

There is a file whose ORGANISATION is INDEXED.you want to read the records from the file in RANDOM fashion as well as sequentially. Then which of the access mode would you specify? a.SEQUENTIAL b.RANDOM c.DYNAMIC d .ACCESS MODE has nothing to do with it
jassi
- Oct 4th, 2007
Answer is we will go for Dynamic Access Mode. Because dynamic will first start from the record like random access then it will go for sequential access in file. So random and sequential both are done.
