I'm aware of ISHELL; its good for most things...common things like "tail -f"
don't work so well :-)
(gripe: the way that the current directory is managed (not) for sh and
ex commands is goofy )
Back to ISPF processing... of course 3270 is half-duplex, but many
applications can alternate between updating output fields and accepting
input without requiring that the user press the Enter key (eg: the MVS
console). It has been *many* years since I wrote any ISPF dialogs, but it
seems to still be limited in this respect. Perhaps this is the reason why
"OMVS" does its own 3270 datastreams rather than run as an ISPF dialog?
