Re: How were first 5 positions used in RPG III?

From what I recall, at least starting with RPG II, that was just a sequence

Deep memory dive needed here!

I'm maintaining code, adding a change to an RPG III source.

RDi at the latest version has syntax coloring, of course, and there is a
number in positions 1-4 that has been used for a change request reference.

RDi colors the 1st 2 positions as black, the next 2 positions as some kind
of grey, the same syntax color as the entry columns of a File Description
Continuation RENAME.

I went to the RPG/400 documentation and found the following: "Page
(positions 1-2) and Line (positions 3-5). These are the equivalent of
source line number" ILE RPG says those positions can be used as a comment,
which is what I always understood.

Just curious if anyone remembers and can say more - I'm wondering now if I
can even put non-numerics in those columns!

Cheers
Vern
