If you want a break with 3270, why a Rube Goldberg with line mode. Make the application an X11 client instead.
We'd all be better of if SUN's paradigm of the thin client (X11 server) had caught on. -- Shmuel (Seymour J.)

To my mind, the 3270 is probably the biggest remaining problem. I've spent a fair amount of time on a real teletype and using the linemode telnet sessions that a standard telnet client provides. It wouldn't be a huge effort to create the necessary code to make the standard interface to z/OS be a line-mode telnet session, creating a fullscreen environment using curses on demand (it's easy to impose a structured line discipline over a unstructured connection). Providing a utility and set of system calls that could switch on and off 3270 emulation mode on a standard character mode terminal would allow (borrow the 3270 emulation engine from c3270 and build it into the shell application) existing code continue to run as is, and evolve over time. Something like: set ROWS=43; export ROWS set COLS=132;export COLS termmode --type 3270 --model=arbsize (support ROWSxCOLS screen size, or the standard predefined 3270 sizes if no environment vars are present) XEDIT foo Bar a termmode --type nvt ISPF or XEDIT that could work on an ANSI terminal would be really useful. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
