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!
