ON MENU GOSUB (OPS1200 Display and Keyboard Only)
Sets up the keypad for subroutines
Format: ON MENU GOSUB {list of 9 line numbers separated by commas}
Group: Character I/O
Units: none
See also: ON MENU GOTO
This command will automatically wait for the operator to press the function (F1 thru
F9) or ABORT keys on the OPS1200 front panel. Then, depending on the key
depressed, a GOSUB will be done to the corresponding line number specified in the
list of line numbers. If the ABORT key or any other key except F1 thru F9 is
depressed, the control will transfer to the NEXT line in the program. Even if the user
is only trying to sense 2 or 3 keys, he or she must specify the entire list of 9 line
numbers.
This command will only work if the OPS: device has been opened using the OPEN
command.
The following example shows a program using the ON MENU GOSUB command
and setup.
Usage example:
10 ON MENU GOSUB (100,200,300,400,500,600,700,800,900)
20 ? ”FINISHED”
30 END
100 ? “100 OK”
110 RETURN
200 ? “200 OK”
210 RETURN
300 ? “300 OK”
310 RETURN
400 ? “400 OK”
410 RETURN
500 ? “500 OK”
510 RETURN
600 ? “600 OK”
610 RETURN
700 ? “700 OK”
710 RETURN
800 ? “800 OK”
