Practical CL: System Reply Lists
There are times when you can't code around a system message, but at least with this technique you don't have to sit around and wait for it.
Written by Joe Pluta
Can't or won't?
OK, chances are that if you try hard enough you can manage to code around nearly any system message. But there are times when the amount of work required simply isn't practical. I'll give you a real-world example that I've run across on many occasions over the years and show you a relatively easy way to get around the problem, as well as an additional trick that can help in some stricter environments.

RPG Academy: Write Better Code—Tips for Organizing Your Modules and Service Programs
It’s important to keep in mind that the naming conventions are not limited to variables, procedures, and files. Since you’re starting with ILE and building your first modules and service programs, this is the perfect time to start doing it the right way.
Written by Rafael Victória-Pereira
I mentioned that modules should aggregate procedures/functions by action and/or subject. For example, you should put all the functions related to database operations over the inventory files in the same module, while putting all the business logic functions (validations, rules enforcement, etc.) in another module. The next logical step is naming these modules (and the service programs that include them) following a proper naming convention and keeping everything organized in a simple, logical, and practical fashion.
