For example, in the ISPF TSO "Command Shell" (Option 6), when I issue a command that does linemode I/O, why doesn't it the linemode output stay in its split, and let me alternate with editing in the other?
This sort of inversion of the desirable layering of functions is far too typical of IBM design. I suspect it has much to do with the two branch technique TSO uses to preserve the integrity of authorized commands. >I thought it might be nice to write an OMVS replacement as an ISPF dialog, >but it is not obvious to me that it is very easy to do... > >What you would like is a multithreaded (multiple TCBs under z/OS) ISPF >application - one thread handles normal input processing, and the other >updates a temporary scrollable table with the output as it arrives.

And I'll repeat my wish for "background initiated foreground". x3270 is open source; it could be recast to operate as an agent so an x3270 invoked on the mainframe might open an X11 window on the desktop. As many concurrent sessions as one wishes, even on a single host. The hard part is getting TSO to talk to sockets instead of to VTAM. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
