Re: RNF7534-Files should be closed explicitly whenNOMAIN is specifiedonthe Control specification.

NOMAIN modules don't have a complete RPG cycle, but they do have most of
the *INIT part.  Implicit closing is done as part of the *TERM part of
the cycle which NOMAIN modules don't have.

The ILE RPG Reference shows the processing sequence for a subprocedure. 
This applies to subprocedures in any type of RPG module, NOMAIN or not.

Compare that to the detailed Program Cycle; the *INIT step is similar to
the initialization activities done when the first subprocedure is called
in a NOMAIN module.
