The short answer is that you really can't do that effectively, unless the list
of files is the library is known to be relatively small.  Most data libraries
will probalby have more files than the command prompter will accept from a
choice program.

Do you have any idea how many files are in the libraries?

Secondly, as also mentioned here, the choice program is not told the contents of
any parameters, so you have no simple way of knowing which library to supply the
filenames for.

The way you do that is by creating a Prompt Override Program (or POP), and
making the library parameter a "key parameter".  This makes it get prompted
separately first, prior to asking for non-key parameters (like FILE in this
case).  Your POP would then have to write the library somewhere -- say a data
area in QTEMP -- and the choice pgm for the FILE keyword could then pull the
library name from the QTEMP data area.

POP's are also described in the manual on how to define commands, and somebody
already posted that link.

Even with the library name, your choice program will still have the size
limitation.  And beyond that, the user can't directly select from the list with
the mouse or cursor -- they have to rekey the name from the list displayed.
