Well, when I first listed the block, the monitor screen flicked, as if the video source was being inter- upted. So? Probably as short power interruption. Then I tried to switch from a disassembled listing to a hex dump and... blank, blink, blink... guru. I rebooted and tried it again and got the exact same results. Just out of curiousity: Does anyone know why this happens? Jeff M. v089pfrb@ubvmsd.bitnet
