ASCII Unit Program:
10 OPEN #2,"SCRN:(40)"
20 PC READ "@R,10,1,B0";R
30 IF R = 0 THEN RS$ = "OFF"
ELSE RS$ = "ON"
40 PRINT #2,"RELAY = ";RS$
Remarks:
The PC READ "@..." statement is used with "@R" as the first argument di-
recting the read statement to obtain the data from the PC Relay memory
area.
Purpose: To input data from a bar code reader using the PC WRITE state-
ment
