How to Pass the DSN name to a JCL during runtime?

Hi,
My job creates a flat file with the DSN names in my first step. I need to use this DSN in the Second step as a input for copying it to another file.

Do we have some method for handling this situation? Please Suggest.

suggest splitting the process into two jobs.

1st JOB:

STEP1:create flat file with DSN
STEP2:create and SUBMIT jcl for second job using DSN created in STEP1

2nd Job: your original second step - file copy

Hi Dick,
Thanks for the response.

Can you please tell me how can the STEP2 in Job1 can be done during runtime without manual interruption?

Are u meaning that, I need to use either a COBOL/any program that generates the JCL?

If so, How can I submit the second job at a stretch.

Please can you give me an example.

you could write a COBOL pgm or a REXX Script.
check the TSO/ISPF/REXX forum. there are plenty REXX of examples.

COBOL would have to write to INTRDR, the REXX Script would SUBMIT.
