Hello, I see another developer on here. And we send our product out using TSO XMIT. Which gives rise to a question. I saw some techie state that he would not install a product unless he could use SMP/E. Is this something us developers should explore or is it a big headache that is not worth it?

Good default in very old days, but not very bad today. Note, The difference between ~3k and optimal ~27k seem to be large, but the effects (performance, space used) give no big difference. BTW: DB2, LOGGER, MQ, and many many VSAM exploiters do use blocks 4kB. Is it far from 3kB? Of course you can try the above datasets with other (SDB) blocksize, and I bet nothing will break. Why didn't they change it? Well, it time to re-start the following subthreads: - TSO is moribound - if it isn't broken don't fix it (see latest implementation as IMBED for catalogs).
