How about logging in on an emulated 3270, setting X11 DISPLAY back to your desktop and starting Xterm under OMVS? The trick would be to bootleg DISPLAY and Xauth through the 3270 logon. I recall that years ago, when security was more casual, I could start Xterm from a batch job. If, only, ISPF would consider operating from other than the logged-in terminal! Long ago, there was ISPGUI (is there still?) Sucked. I once started an ISPGUI from a batch job. Ran into an impasse: Couldn't reply to some message. Went to SR who said, "You need to reply to that from the 3270 you logged in with." "I didn't log in with a 3270." "WTF! Impossible! You must have logged in with a 3270!" IBM doesn't sympathize. How about a dynamically resizable 3270 in an ISPF session!? (XEDIT comes close: I can pull the plug on an XEDIT session and reconnect with a different terminal geometry. XEDIT dutifully repaints the screen to the new geometry. What about ISPF? ISPF people say, "Impossible! NFW!" No. Just do a WSF Query, as XEDIT does, and redraw the display. As it is, I get a recurrent "Terminal Input Error." Can't even get to a READY prompt to LOGOFF.) Long ago, there was SimWare. (Are they still? Who bought them?) Ran in a VM service machine and emulated a 3270 at the host. A later release performed the emulation at the desktop. Slower; it transmitted the entire screen, not just modified data. But at least one co-worker preferred it that way: even though overall response took longer, he preferred not to see the screen updating incrementally. A co-worker once had nedit (X11) working under OMVS. Has anyone got jedit working? Forget Session Managers. Why not simply support concurrent logins as any non-IBM OS does? -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
