My guess is that the 3277-1 was for retail applications. -- Shmuel (Seymour J.) Metz http://mason.gmu.edu/~smetz3 עַם יִשְׂרָאֵל חַי נֵ֣צַח יִשְׂרָאֵ֔ל לֹ֥א יְשַׁקֵּ֖ר

It supported 2741s, 2260s (mod 3s, 12x80), and ASCII terminals. No 3270s. So I think my original question was misguided, though the answers have been fascinating! Sounds like the 3277-1 was sort of an answer looking for a problem, and the -2 got to something usable. -----Original Message----- From: IBM Mainframe Assembler List <ASSEMBLER-LIST@LISTSERV.UGA.EDU> On Behalf Of Phil Smith III Sent: Tuesday, August 26, 2025 11:36 PM To: ASSEMBLER-LIST@LISTSERV.UGA.EDU Subject: Re: 3277-1 XEDIT will still wrap lines if you SET VERIFY to a value greater than the physical screen size, sure. I asked my oldest contact from UofW (in his 80s) and he doesn't remember what WITS used. WYLBUR, now that I think on't, was definitely linemode: change "x" to "y" in "z" But he *thinks* WITS was also linemode, probably on 2741s. Pre-tube. I guess I'm showing my (relative lack of) age by thinking "it must have been on a screen"! -----Original Message----- From: IBM Mainframe Assembler List <ASSEMBLER-LIST@LISTSERV.UGA.EDU> On Behalf Of Paul Gilmartin Sent: Tuesday, August 26, 2025 10:28 PM To: ASSEMBLER-LIST@LISTSERV.UGA.EDU Subject: Re: 3277-1 On 8/26/25 19:21, Phil Smith III wrote: > The 3277-1 was 12x40.

When I first used XEDIT it wrapped lines, depending on the bounds setting. I believe ISPF never (even to this day) got the wrap ability. The developers simply waited for larger terminals. But still, LRECL allows lines longer than any terminal. -- gil
