Re: ESPIE question (does ESPIE "cover" ATTACH'd sub-tasks)

ESPIE beats everything. That's the point. If (a.) all you need to trap is program checks; and (b.) you expect a bunch of them -- use ESPIE. I'd say "If ...you expect a bunch of them" then make every effort to redesign your application. Because "no program check" can be thought to beat ESPIE

Re: ESPIE question (does ESPIE "cover" ATTACH'd sub-tasks)

A TP followed by a conditional branch is more expensive then having no instruction there. So it depends on exactly what you're doing and the percent of bad data which approach is least expensive. OTOH, an inexperienced programmer is more likely to get it right with TP. _

Re: Free 3270 emulator for Mac OS

A few more notes on nomenclature. TN3270 and TN3270E (upper case) are protocols published by the IETF; programs implimenting those protocols are TN3270 clients, not TN3270 emulators. TN3270 clients are not 3270 emulators, because they do not support any of the link protocols that real 3270s do,
