We used some instruction sequence like this to communicate with the operator: * ASK OPERATOR WHAT NEXT: H 111,111 LOAD 1's into A + B Address ASK BSS MONTHLY,1 START MONTHLY TOTALS IF SENSE-SW=1 BSS DAILY,2 RUN DAILY IF SENSE-SW=2 EOJ H 999,999 LOAD 9's into A + B Address B EOJ END OF JOB The Halt ("H") would freeze all flashing lights on the console, the A and B address lights would display the fake address (1's, 9's) in binary. The operator would wake up, realize what happened, look up the operations manual or Job Setup sheet, flick the requested toggle switches up/down, press the "Start" button, ...and doze off again. Now, don't be too hard on Shmuel, he has written a few, somewhat more useful posts in the past...:-). Andreas F.
