Optional parameter on CL Program

I have a CL program that is called by many other programs. It currently accepts a single parameter, but I would like to add a second parameter w/out having to change all of the calling programs.

I have thought of a few ways to do this, but wanted to see if I'm missing any other angles.


1. Simply create a copy of the CL pgm that accepts a second parameter
2. Add the parameter and monitor for a message
3. Create an RPG program of the same name and "wrap" that around a renamed version of the CL pgm

Thx,
Greg
