RE: Ok here is a challenge

seems this could do the trick.

the documentation says:

--snip--
Prompt override program

You can write prompt override programs to supply current values for 
parameter defaults when prompting the command. 

For example, prompt override programs are frequently used on Change 
commands to supply values for parameters with a default value of *SAME. A 
prompt override program is optional.
--snip--

for me this reads, as if these prompt override programs supply you the 
list of valid parameter values you see, when you press f4.
if so, this would be what the "guru" meant.

btw: which rpg guru isn't on this list?

Are you referring to a prompt override program?
