If you make errors entering a CONTROL command, the audible alarm
sounds, and the command appears in the entry area. The location of
the cursor indicates the error:
- If the error is an invalid operand, the cursor appears under the
invalid operand:
CONTROL X,N
- If the error is an invalid erase request, the cursor appears under
the first invalid request.
CONTROL E,31,19
- If the CONTROL command exceeds 126 characters, the cursor appears
at location 127 in the entry area.
To correct any of these errors, use the procedures described under Changing information in the entry area.
If the system detects an error in a command other than a CONTROL
command, it writes the command in the message area with an error message.
Follow the procedures indicated for the error message in the MVS™ System
Messages books.
