You have obviously not read AND understood Robert's reply. What follows your //SYSIN DD * is not JCL but IDCAMS control cards.

I understood that. But then if I don't ask the question right way, how should I ask such a question?

Hi,

Program-A CALLs another Program-B statically. Program-B has variable B1 defined as

B1=0
B1=B1+1

After 4th CALL what is the value of the B1?

If the Program-B was CALLed dynemically, what will be the value of B1?

I said, it will be 4 in both the cases. But I was told I am wrong. Interviewer ...

HI,

I have used the following JCL


//STEP1 EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
ALTER my.file -
NEWNAME(my.new.file)

Is there a possibility to rename a dataset name in JCL itself? Can you please suggest a sample code.
