Again another option is to take advantage of being able to send different
numbers of parameters to an RPG program. It is, admittedly, a 'cute'
technique, requiring special, esoteric, knowledge. It happens to be a
technique many of our programs use. They have a return code, then a data
structure or several variables. If the parameter count = 1, this means
shutdown.

I agree—this is not an easy maintenance technique. It falls into that
category of 'CUTE', meaning unmaintainable. However, it's present in lots
of our stuff, mostly things generated by Genesis, a code generation tool
(won't say what I think of the product—oops, guess I kinda just did! <g>).
