Working Storage Definition
Consider the follwing snippet:01 WS-VAR USAGE IS INDEXIs this a valid working storage definition?Justify your answer

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

Hi, This is not a Valid definition bcz the USAGE IS INDEX clause is used to provide an optimized table subscript. When a table is the target of a SEARCH statement it must have an associate...

How will you analyze a COBOL program?
Hi,
I was asked in interview how would you analyze a COBOL program?
I gave the ans as there are many kind of analyses -:
Requirement analysis
Root cause analysis
Impact Analysis
Problem / logic analysis

Second part of your answer seems satisfactory. You should have asked the interviewer for what we need to analyze, if its just for document purpose, then your answer is right. If its for a change, then there are specific areas we need to analyze for the changes impact.

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.

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.

Hi,? Up to my knowledge, compute can handle only numeric items. But Move statement is having capability to handle numeric, alphabatic and alphanumeric items.ThanksP.Karthikkumar

1. Yes allowed. why because only one file description is allowed in a FD, but file is a collection of records. 6. comp-2 occupies 8 bytes .7. Max length of a numeric item 18 digits.

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...
varanasi
- Jul 5th, 2006
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.
