The 3290 added what I think was called "DFT", or "partitioned mode" to the 3270 protocol, and allowed a smart application (afaik, ISPF is the only application that smart) to divide up the screen into several logical screens. The ISPF SPLITV command implemented that. Maybe some TN3270 apps can support it, but I haven't explored it, as multiple sessions are better anyway.
I used a 3290 for a while in the Naughty 90s, and liked it, except for the orange display. The 3290 was a gas-plasma or something like that, so the color was chosen by physics, not aesthetics. sas On Fri, Apr 16, 2021 at 4:47 PM Ed Jaffe <[email protected]> wrote: > On 4/16/2021 1:43 PM, Bob Bridges wrote: > > Somewhere in the dim reaches of my past I think I saw mention of the > ability to split an ISPF screen vertically rather than horizontally.
