Thanks Ed, that helps. So a typical "old style" PTF for DFSORT, which added several new functions to the product would have been an SPE, either by name or by fact.
And, even with the OS on a two-year release cycle, new functions (for anything) can be provided (delivered) at any point (continuously) without having to wait for X months for the new release. That's good. It'll keep many contributors here busy, even if IBM doesn't manage the "update every 11.6 seconds" of Amazon :-) ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
