Hi, outthere, I have a system set up with installbeep in the startup sequence. This will play a beep, rather then flashing the screen at an error. But unfortunately, I use BASIC once in a while (draw sinewaves, fourier etc) and it has a beep built-in with its screen flash. Now that crashes the computer! Gomf catches it, but can't solve it. the Error is a LINE F SIMULATION, and occurs in one of the sound-channel interrupts (says Xoper) What can I do to get rid of this stupid CRASH!!! (Is it possible to deactivat installbeep, or give it a low-low priority orso?) Any help is welcome, Nils Gokemeijer (NJ_GOKEMEIJE@FANDM.bitnet)

I've found that multiple beeps at once or a beep while some other program is beeping can wedge my machine when I'm running InstallBeep. My only solution was to remove InstallBeep. The problem occurs when BASIC and something else both beep at the same time, yes? -- Darren -- --- Darren New --- Grad Student --- CIS --- Univ. of Delaware --- ----- Network Protocols, Graphics, Programming Languages, Formal Description Techniques (esp.

My error was in opening the device in the main program, and then using it in the SetFunction()ed routine, assuming that only one beep would happen at a time. Unfortunately, the call to DisplayBeep that I intercepted can be called from anywhere, causing the program to try to use the device twice, resulting in a GURU. AmigaBasic, I found out, calls DisplayBeep twice in rapid succession, showing the proble consistently. -larry -- The only things to survive a nuclear war will be cockroaches and IBM PCs. +-----------------------------------------------------------------------+ | // Larry Phillips | | \X/ lphillips@lpami.wimsey.bc.ca -or- uunet!van-bc!lpami!lphillips | | COMPUSERVE: 76703,4322 -or- 76703.4322@compuserve.com | +-----------------------------------------------------------------------+
