Re: Global variable search

You do really need a change management system! Or a cross-reference tool!

OK - I said it!

But since you don't, think about how things are defined in RPG IV 
source. You will have to use a program to read through each record of 
the source member. You know how to specify different members to be 
processed, I know.

First, a prototyped main is going to have PR in a certain position of D 
specs. So you have a test for a prototype. Then the name will be the 
same as the program - it will be 10 characters and somewhere near the 
beginning of the D spec with PR in the right place.

As to global variables, well, they are in D specs outside of any 
subprocedures. As soon as you hit a P spec, you are done working with 
global variables.

This is a quick think on the process - there are probably other issues. 
You might want to find any program-defined variables, if any are still 
in use. Don't assume anything. Those defined in the main procedure are 
global, I think. I don't remember whether one can have program-defined 
variables in subprocedures - haven't used such a variable in maybe a 
decade, at least.
