What do you mean by a "dynamic dataset"?

datasets that are created through program (e.g. cobol) if some condition satisfies.

Thanks

hi,

You can't have SO CALLED dynamic datasets in the JCL coz they should be created at run time.
All you need to do is...write a cobol program which edits the JCL(JCL is the INPUT) and write the Dynamic Datasets using the CObol and Submit it using Internal Reader.

You can use some forms of dynamic allocation from within COBOL. For example:
- BPXWDYN
- TSO's ALLOCATE command
- SVC99 call

The documentation of BPXWDYN can be found here.

ALLOCATE is a TSO command that can be found in the fine manual. An example of how to invokw TSO commands from within COBOL can be found here.
