Just set bit 0 of byte 80 of an alpha image to enable debug; clear it to disable debug. I've put VFE online to allow this. I did the change with forcex.exe in my area with: $vfe:==$vfe $vfe/write forcex.exe *c 80,29 ! to set debug on, note WAS 28. *w ^Z $ To set nodebug vfe/write forcex.exe *c 80,28 *w ^Z Where "*" represents the prompt, which now that I look is actually 1> for the first VBN. VFE has a HELP command to show how to use it. It may be possible to get it to run from a command file; I haven't tried that. Glenn
