RE: EXTFLD Question -- RPG400-L

When I see "MMVI" I know it is 2006, but do all others who come after me?
Maybe.
When I see an @ or $ or # in a variable name, I see System/3 RPGII legacy code
that's been ported and my first instinct is to delete it and rewrite it.

Okay thanks... that's what I was looking for.  RBFUTUSEA is defined in a
file on the FSPEC.

As for the "@", I'm just copying code from other renames, keep it uniform.
But why does it suck so bad?  It's not a big deal.  When I see the "@", I
immediately know that the field is program described. Also, the last time I
checked, you can't begin a field with a number. Maybe that's changed with
V5R3.

Once you override the external field name using EXTFLD, that name no longer
exists in the program.
If you are able to refer to RBFUTUSEA in your code, then you have it
defined
elsewhere in the program, probably via a file or another data structure.
In either case, RBFUTUSEA does not exist in the 12DBRC data structure ("at
signs" in names suck, by the way) and therefore moving anything into it,
does
not get reflected in FutureUseA or its overlaid subfields.

D @12DBRC       E DS                  EXTNAME(BEF012)
D  FutureUseA   E                     ExtFld (RBFUTUSEA)
D   ProdPlantYN                  1    OverLay(FutureUseA:1)
D   FutureUseA2                  9    OverLay(FutureUseA:*NEXT)

We have a future use field in a file that we are going to begin to use.  I
only need to use one character of it.  Anyway, I was under the impression
that I can use FutureUseA in the program as it was RBFUTUSEA, so that when
an update was executed the RBFUTUSEA field will be changed to what was in
FutureUseA.  To break up the field, I used the Overlay for ProdPlantYN.

When the program executes, ProdPlantYN is populated to 'Y' and while in
debug mode, FutureUseA = 'Y         ', however, This value doesn't get
updated to RBFUTUSEA.  Am I suppose to move it there?  I thought the
purpose of ExtFld was to rename the field for the program?  Is there
something I'm doing wrong?

NOTE: BEF012 is defined in the FSPEC, but there is NOT a prefix on it.

Thanks in advance.
