Prompt for user input at runtime

With most CL procedures and programs, the workstation user provides input to the procedure or program by specifying parameter values passed to the procedure or program or by typing into input-capable fields on a display prompt.

You can also 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 procedure or program source, the system displays a prompt for the CL command. Parameter values you have already specified in your procedure or 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 program source which CL command is to be used at processing time.
