"Loading a huge data set into the editor would allocate a huge number frames" is part of the discussion and is a clear reference to real storage.

Well, the discussion eventually was talking about editing large MVS data sets or UNIX files using ISPF edit. For ISPF edit (and view) the current limiting factor is virtual storage, not real storage. ISPF edit is AMODE31, and thus cannot deal with above the bar storage. So all the real frame services (PGxxxx) don't help. Windowing techniques would allow to edit/view data sets / files of any size. -- Peter Hunkeler ---------------------------------------------------------------------- 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
