> Can TGET NOWAIT simulate that look-and-feel? Il va dsans dire. Maybe the MVS-OE developers should have look at CMS in addtion to reading up on the TSO macros. OTOH, maybe they shoukld have been familiar with the MVS and Eunix worlds in general; it wasn't well integrated with classic MVS, and no matter how popular, if it wasn't in POSIX or XOOPEN it didn't make the cut.
> The REFRESH key is better: less disruptive. ATTN is *so* 20th Century. WTF? There is no "REFRESH" key on the 3270, there is only a PA key that you've told the software to treat as a refresh. In what regard is, e.g., PA2, more modern than ATTN? If anything, ATTN is more modern, and it doesn't require that the program first unlock the keyboard in the WCC. -- Shmuel (Seymour J.)

Can TGET NOWAIT simulate that look-and-feel? (I've rearranged quotations below. I believe I haven't distorted context. Check archives for accuracy.)

Pragmatic users can use SSH and zFS directories; the masochists can stay with 3270 OMVS and PDS. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
