But if the panel is displayed in LOCK mode this means a user can't enter any data; i.e. the entire mainframe session is locked. I doubt this is what you want, so in short, you're stuck with it working the way you already have it. >> >That's *so* twentieth century! > >Since the advocates often argue that mainframes are more economical >than small systems, why is this feature readily available on desktops, >but not on mainframes where it should be cheaper? I think this is an artifact that the 3270 data stream is really designed to be "half duplex", like the old walkie-talkies. Each side tells the other that it has control of the transmission. This is especially true in TSO. Now, I do remember z/VM's or maybe CMS's control of the 3270 was more "full duplex" like. > >There's one ISPF function (I forget which) that lately shows a >progress bar. > >It's a continual source of irritation that I can't put SCSV in >auto-refresh and go edit a file in the other split. Again, since ISPF is a TSO application, it is held hostage to TSO's poor terminal I/O paradigm. > >It's a continual source of irritation that I can't split between >OMVS and Edit, for example. Complain to the OMVS developers. OMVS is not an ISPF application. It is a native TSO application. Native TSO applications do not support split screen. > >Why does DDLIST show the message, "Searching data sets not on screen" >rather than scrolling so they appear? > <snip> >I believe that nowadays much of the duplex interaction would be possible >with modern 3270s. VTAM is much the culprit for prohibiting it. Actually, I think it is more TSO, but maybe VTAM as well. z/OS consoles certainly do "full duplex" fairly well. > >Why is horizontal scrolling so much more difficult than vertical scrolling >in ISPF?
