It seems I'm having a senior moment.
For years, I used to allocate data sets in ISPF 3.2, leaving the block size
field empty. The system then calculated the block size based on RECFM anf
LRECL. The result was half track blocking.
At my new employer, I get the block size set to maximum (for RECFM & LRECL), so
FB-80 leads to 32720. This is z/OS V2.1. This is only via ISPF 3.2; in batch, I
still get half track blocking.
What am I missing?
FWIW,
I get blocksize 32720 on my z/OS V1R4 system. Yes, I have V1R4 running
on my trusty old P390.
