In addition to all of the other translations that may be invoked, a 3270 with text or APL has two built-in code pages and uses the GE character to select the alternate page. ISPF has to deal with that if you select the appropriate terminal type.

I would have naively assumed that the A/E translation is happening between the TN3270* protocol and the in memory screen buffer. This would mean that the buffer can be displayed with any font the user chooses /and/ it would more cleanly support copy / paste. *I actually assume that similar would happen with communications using more traditional SNA on the LAN; e.g. DLC. -- If memory even remotely serves after a long day. -- Grant. . . . unix || die ---------------------------------------------------------------------- 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
