} "resizing to 24 by 80" is done by the application using the "write" vs } "write alternate" form of the command code. Correction Don, its erase write and erase write alternate. For the non-3270 internals folks, all 3270 displays (except model 2s (24x80)) have 2 sizes. 24x80 and another size. On real 3270s, there were only a few "other" sizes, such as 32x80 (model 3), 43x80 (model 4) or 27x?? (model 5). On PC based emulators, many other sizes are possible. On all of them, if an erase write command is recieved, the display reverts to 24x80, and if an erase write alternate command is recieved, the display goes to the other size. Since VM:Backup wants to display its screens on 24x80 screens, it sends an erase write first. When VM:Backup ends, either it or CP sends an erase write alternate to reset the screen to what you had before. ISTR that part of CP's response to the CLEAR key is to send an erase write alternate. -- Rich Greenberg N Ft Myers, FL, USA richgr atsign panix.com + 1 239 543 1353 Eastern time.
