You're right that it's generated by CP. I thought that by doing SIO with command code X'0B' I'd be able to avoid the text, but NNOOOOO. Legend says that it's kind of an inside joke with the VM developers in that one of the real consoles on some older model of 370 (who's number escapes me) had an obnoxious fire alarm style bell. GONE EXEC (and probably others) mask it by SAYing '1D1C'X before and '1DF0'X after invoking BEEP. Those are 3270 orders which set the attributes to "no display" and "display" respectively, so the verbose "RRRR....RING....GGGG" still shows up in your console log (if SPOOLed), but not on your screen. You could probably write your own BEEP which would spit those out using X'09' with the X'0B' in between. Rick Troth ------------- Rice ONCS VM Systems Support
