Jeff,
I didn't realize that the two methods behaved differently. Hence, that's
why I got the error thrown at initialization. I'm going to pull all the
code into the C-specs (as Charles suggested) and have a go with that.
BTW Jerry, I meant RPGIII, not RPGIV. Sorry...

Buzz,
You can define the LDA in RPGIII using the *NAMVAR DEFN in your "C" specs.
The following is an example:
ILDA DS
C *NAMVAR DEFN *LDA LDA
C IN LDA
By specifing *LDA in factor 2, you are indicating the the Local Data Area is
to be used.
The UDS on the "I" spec indicated an implictly defined Data Area Data
Structure. By leaving out the name on the "I" spec, the system understood
that it was to use the Local Data Area.
The use of UDS to define a Data Area Data Structure implied a Read (IN) at
the start of the program and a Write (OUT) at the end.
There is no requirement for using that method other than the desire to avoid
the *NAMVAR statement and coding the IN and OUT functions yourself.
Hope this helps,

Buzz,
Did you mean RPG III? RPG IV is not OPM.
If it is RPG III, is converting it to IV out of the question? Once it's
in IV, you can do what Charles suggested.

Charles, the program in question is an OPM RPG IV program. I'm unaware of
an alternate way to define the data area data structure other than to use
"UDS".

Buzz,
There's an implicit IN *LOCK done by the cycle, along with an implicit
OUT,
on a UDS.
To prevent, remove the U and use the DTAARA keyword on the define.
HTH,
Charles
