Hi,

In JCL,

I wrote like this,

//out2 dd dsn=xyz.abc.out2.se,
// disp=shr
//out3 dd dsn=*.out2,
// disp=shr,
// vol=ref=*.out2

all these in only one step.
what does out3 dsn refer to ?

Why did you do this?

If you explain what you are trying to accomplish, we can provide relies you may find more useful.

If you have not done so already, you need to download (or set bookmarks to) the JCL Reference Manual and the User Guide.
