With most CL programs and procedures, the workstation
user provides input by specifying command parameter values that are passed
to the program or by typing into input-capable fields on a display prompt.
You can prompt the workstation user for input to
a CL procedure or program in the following ways:
- If you enter a ? before the CL
command in the CL source program, the system displays a prompt for the CL
command. Parameter values you have already specified in your source program
are filled in and cannot be changed by the workstation user.
- If you call the QCMDEXC program and request selective
prompting, the system displays a prompt for a CL command, but you need not
specify in the CL source program which CL command is to be used at processing
time.
