>> IF you are using ILE COBOL (RPG does not have external sharing of files
and data structures) and IF they are both called from the same job, and IF
they are in the same activation group, then anything that ProgramB changes,
ProgramA will see.

One correction and one simplification.

"RPG does not have external sharing of files and data structures" is only
partly true.  RPG cannot share files but most certainly can share Data
Structures (check out the IMPORT and EXPORT keywords for confirmation.

The part of the statement "IF they are both called from the same job" is
superfluous.  If they are in the same AG they are by definition in the same
Job since the AG is a subdivision of the Job.

Since files are not involved in the scenario in question, that means that we
can say: IF they are in the same activation group, then anything that
ProgramB changes, ProgramA will see.

Just a bit simpler.
