I hope you are not suggesting a single parameter to hold all 3 input values - overloading like this is a risky technique, in my opinion. Now if there is a data structure on both ends to which it can be moved, OK, that's better. And it's probably needed when working with OPM RPG.

Fisrtly, if the parameters are already given, I am not sure what freedom you may have.
Secondly, I would attempt to use a string for input and output - one rpg or cl "parameter" covering the numerous given "parameters".

Subject: function with a bunch of parameters


Hi all,

When I first discovered this list, I started a discussion that made Alan Campin's stomach turn. It was remembering these last two words that helped me refind the discussion in the archives.

I was particularly impressed by Alan's response here : http://archive.midrange.com/rpg400-l/200706/msg00363.html

I've kept that in mind ever since and I'm sure that my programs have improved because of this approach. However, I've just been given a function to write where the parameters are already given for me. Alarm bells are ringing.

Here's my list of parameters

Input

Product code
Date (to see if the tax was applied at that time )
Cost before taxes

Output

Cost with all taxes applied
Total of all different taxes
MODS details of each tax applied:
Tax code
Tax type
Tax rate (%)
Tax total (EUR)


I'd be interested to know how you'd go about reducing the size of this bunch of parameters. A lot of RPG400 will need this information.
