I thought in order to be ILE RPG it had to use service programs,
methods/calls to other languages (such as C or Java), binding, or
such. That is, a program that was just, to say simply, Read-a-Record
and Write-a-Record was *just* RPG IV. Or is a simple inquiry (data
file, display file, some logic, nothing else really) write in IV
syntax an ILE program?

"RPG IV" is the name of the language and "ILE RPG" is the name of the RPG IV compiler on IBM i.

A case can be made that a DFTACTGRP(*YES) program is less ILE than all other RPG IV programs. The system handles these programs different with respect to exception handling and static storage deactivation, so they really can be said to be more OPM-like than ILE-like. But even DFTACTGRP(*YES) programs use binding directories, service programs, and calls to other languages under the covers, since they use the RPG runtime the same as all RPG IV programs.

In my opinion, DFTACTGRP(*NO | *YES) is the only line to be drawn between ILE and non-ILE. That's when activation groups come into play. I think that whatever else a DFTACTGRP(*NO) program does can't make it any more ILE than if it just does an immediate RETURN.
