Global just means static storage. It never goes away.

You can have static storage in a subprocedure that is not global. So
TRUE : all global storage is static storage
FALSE: all static storage is global storage


An interesting question that maybe Barbara can answer is when does the
static storage go away when a program using the main keyword ends.
...
So the question becomes when does the storage get released?


The static storage gets released when the activation group ends.

RPG has three types of modules:
- cycle main (main procedure uses the RPG cycle)
- linear main (main procedure does not use the RPG cycle)
- NOMAIN - there is no main procedure

A linear-main module has much more in common with a NOMAIN module
- no cycle - *INLR doesn't any special meaning
- no implicit closing of files
- no implicit unlocking of data areas
than with a cycle-main module
- has a program-entry procedure

I know that static storage does not go away when a program using the main
keyword ends.

When a DFTACTGRP(*NO) cycle-main program sets on LR, its static storage does not get released. Instead, the static storage gets reinitialized by RPG when the main procedure gets called again.
