Good point, Nathan - my intent was to speak of a code unit. But the word, "global", is used in the RPG documentation, therefore, I'll stay with it for the purpose of this discussion - so long as it is understood as I just stated.

I'll throw out a suggestion just for terminology sake. I prefer to call
module-level declarations, "module-level declarations", as opposed to
"procedure-level declarations", and rather than "global declarations". To me a
global declaration would be something that might be shared across an entire
activation group, which might include any number of programs and service
programs in a call stack. Say you export a data structure from a service
program, for example, which is intended to be shared across an entire activation
group. That's a lot more global than "module-level" declarations.

Subject: More on global declarations in RPG IV

In a recent thread, there was some question about global variables,
etc., when using the MAIN control keyword. I had mentioned that some
things still must be global. I believe that one of them is compile-time
arrays. If you want to find all the messages that deal with "global",
here's a way to do that -

Execute the following command -

DSPMSGD RANGE(*ALL) MSGF(QDEVTOOLS/QRPGLEMSG) DETAIL(*FULL) OUTPUT(*PRINT)

Then you can search for 'lobal' in the spooled file - this covers
possible upper- or lower-case "G" in the word "global"

So have fun. And I did find, in the RPG ILE Reference, this note about
CTDATA, footnote 2

This keyword applies only to global definitions.

Random musings while on vacation! I know, I'm rubbing it in!
