Chuck, Why use INCLUDE MEMBER= in a second job? A sequential dataset will do just as well to build the entire JCL you need, including the dynamically generated tape allocations, then just write the whole thing to an internal reader. KISS principle.

Thanks John! I hadn't gotten to the DYNALLOC support yet. That was the agenda for this morning. It appears that I can't "get there from here" as the saying goes. I have thought of another means of doing what I what, I just didn't want to do it. I was hoping to have my solution be a single job. The way I was thinking of getting around it would be to allocate a small PDS and generate the JCL I need to concatenate the datasets with the UNIT=AFF specified and then in the second job do an INCLUDE MEMBER= in the job step that needs the concatenated datasets. To me that's a clunky solution, but it works. Back to the drawing board!
