RESPONSE ARM SRQ TRIGGER STEP RECORD
EXAMPLES 100 PRINT#1,"ARM SRQ" Enable SRQ Condition
110 T = TIMER
110 IF LOC(1) THEN PRINT INPUT$(LOC(1),1);
120 IF TIMER - T < 5 GOTO 110

5 seconds after receipt of the ARM command.
PRINT #1,"ARM SRQ STEP" Arm SRQ and STEP.
PRINT #1,"ARM?" Query armed status.
INPUT #1, A$ Get response.
