Creating Commands

Hi,

 

One of the features of OS/400 commands that I really like is how a command,
like CPYTOIMPF for example, only displays part of the command parameters
until you press F9 (All Parameters).    Another cool feature is a command
like DSPOBJD.  When you enter *OUTFILE in the Output parameter and press the
Enter key, you are automatically prompted to enter an OUTFILE name and
library. If you don't enter *OUTFILE in the OUTPUT parameter, you never see
those additional parms.

 

 

Is there a way to duplicate this functionality in user created commands?
I've been playing around with it a little bit today and so far have not
figured out the right combination of parameters on the PARM keyword in my
command source.

 

Can anyone tell me how this functionality is achieved?

 

Thank you,
