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 refuse...

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.
