Command Choice Program

["Peter Clifford" <peter.clifford@xxxxxxxxxxxxxxxxxxxxx>]

The parameters to a command choice program include the name of the command 
and the keyword of the parameter for which choice text or possible values 
are to be retrieved. In theory this allows a single program to be used as 
the choice program for several commands/parameters.

My problem is that I need to use a choice program for different elements of 
some complex list parameters, e.g.:

                    PARM       KWD(PARAM) TYPE(L_PARAM)

L_PARM:     ELEM       TYPE(*CHAR) LEN(1) CHOICE(*PGM) +
                        CHOICEPGM(CHOICEPGMA)

                    ELEM       TYPE(*CHAR) LEN(1) CHOICE(*PGM) +
                        CHOICEPGM(CHOICEPGMB)

Question:

So far as I can make out, I'm stuck with having two choice control programs 
here (CHOICEPGMA and CHOICEPGMB) as, so far as I can tell, there is no way 
of telling from the program parameters which list element the call relates 
to. Anyone know better?

It would be very nice if IBM could add an extra parameter, e.g. a number 
indicating which element of the parameter the call relates to, where the 
parameter is a list parameter. This would reduce the number of objects 
required by our system by about a dozen. We already have a generic choice 
control program, which is called by the various actual choice control 
programs used by our commands in the circumstances above, but the problem is 
we are still left with multiple choice programs because of the issue 
described above (albeit very trivial ones).
