Sorry for the delay in responding to this.  You might look into using
the ALTTAPE parm to have DDR "spill" to another tape volume
automagically.  This works, but unfortunately it ties up TWO tape drives
for what is essentially a single tape dump "stream".

I modified DDR so the EOT condition triggers a REXX EXEC that mounts a
scratch tape (using VMTAPE and DFSMS/RMS) to get around this.

That's where a PIPE version of DDR would help.

My test code didn't have PROMPTS OFF, but my original code does.

In any case, after the DDR completes is too late to react to messages
like 
END OF VOLUME when you want to know what new tape number is being
mounted.
