Referback DDName having concatenated files

ParagChouguley · Posted: Mon Apr 13, 2009 6:14 pm

I have 2 steps. First step has ddname DD1. Second step has ddname DD2. DD1 has 5 files concatenated. Now I want DD2 to be exactly same as DD1. ie. all concatenated files should also be available in DD2.
How do I do that?

Using an INCLUDE would be the safest way to ensure they are the same.

You could try using the *.ddname syntax that refers to previous DD in a step (see page about 12-93 in the MVS JCL Reference). I don't know how this treats concatenated DDs though; it may not work or give erratic results.

I don't recommend using esoteric JCL features like this; because if you ever run a 3rd party tool on your JCL it may not be supported (I know my JCL parser doesn't support it).

Hi Parag,

You have to learn to use the Manuals. The link to them is at the top of this screen.

I found this in the INDEX in under 15 secs:
