Michael, As far as I know, the answer to your question is, YES. Your dynamic allocation request to concatenate datasets is the same whether you dynamically allocated them or if they came pre-allocated at runtime. You always use DDNames in the concatenation list, never dataset names.
Your S99VERB would be S99VRBCC in your DYNALLOC control block. Then, your text unit to allocate 2 DDs, DDN1 and DDNAME2, would be: DC S(DCCDDNAM),S(2),S(5),CL5'DDN01',S(7),CL7'DDNAME2' The "2" is the number of DDNames in the list and the list follows immediately with length/DDName pairs. The text unit, DDName count and DDName lengths are all halfwords. There are some implications with respect to de-concatenation, but you'll need to read up on those yourself. They can be found in the MVS Authorized Assembler Services Guide, Chapter 26. Requesting dynamic allocation functions. Hope this helps.
