The answer is "how much common storage above the line do you have"? I think I looked at this before and the IPL set is in SQA and all the ones after that done dynamically are in ESQA. If ESQA runs out that will flow into ECSA. If really interested, turn on a rexx trace in my IPLINFO, run "IPLINFO LNK" and compare the addresses to a "IPLINFO VMAP". I just defined a new LNKLST on my sandbox and it took about 8K of ESQA. So even if you have a large number of libraries and say you use 15K for each new set (without deleting any), how many of those can you fit in 20M of unused ESQA... or 200M of unused ECSA (math exercise left to the reader). IOW, don't worry... be happy.
