Re: Global variable search

Another way to say it,

RPG doesn't support local variables within the main procedure. Any
variable defined outside of a sub-procedure is global.

The order of the D-Specs doesn't matter.  All D-specs are global till
you hit the first C-spec.

For a variable to be local, it must be within the Beginning/Ending P-specs.

I'm confused.
I guess I too would think the wVar would be local.
What am I missing ?
Once the wVar is defined underneath the PI, within the subprocedure, how
could it be a global var?

a program with this kind of structure :

D Main   PR
D P1 etc

 * Global variables.
D gVar

D Main  PI
D P1 etc

 * Local variables.
D wVar

The programmer did not seem to realise that wVar is global.
