Vis-à-vis fragmentation, I was once tasked with finding the 'largest chunk of free storage' in order to order to set region limit in IEFUSI. I no longer have the code, but I believe I used VSMLIST to scan through available chunks to locate the biggest one. This may be overkill for your needs, but it was very reliable.
The problem being addressed was a shrinking address space that gradually reduced the available storage over time until the initiator was bounced. That problem may be long gone in z/OS, but the technique should still be valid. . . .

But remember that "how much" has several answers: not only "Where?" but "In how big a chunk?". Fragmentation can ruin your day...
