Just make sure that if you have a standalone CPC with CFs for that purpose that

Fortunately ICF as other specialty engines always run at full speed.
That's also reason why one should not use older machines for CF.

The syntax using stepname (not procstep name) is used because there is no
nested procedure in that refer back. By that I mean, the reference is not to a
DD within a proc invoked by the procedure. That is how I've always viewed it.
I reread the JCL manual concerning backward references and it

Second guy wins. Conscientious second guy will create the file with
