The OpDesc feature has never been fully implemented. According to the
docs ...
"The ILE RPG compiler only supports operational descriptors for character
and graphic types. Operational descriptors are not available for arrays or
tables, or for data of type numeric, date, timestamp, basing pointer or
procedure pointer."
So I'm not exactly surprised that this doesn't work.
Have you opened a ticket with IBM to establish if this is a formal
limitation?

Thanks Chris for your comments.
I have made several tests with the CEEDOD and CEEGSI APIs with different
types of parameters. When I specify a data structure with null indicators
it always throws the error CEE0502 Missing operational descriptor.
If I remove OPTIONS(*NULLIND) keyword parameter, the operational
is created. The compiler may not be able to build an operationaldescriptor
of a data structure with nulls.also
Best regards.

Well since it's a data structure, maybe try CEEDOD instead of CEEGSI.
This is because CEEGSI appears to be for Strings, and CEEDOD is for any
data type.
Also, you didn't list the Proto type "PR". You should verify that it
authorincludes the OPDESC keyword.

Subject: Operational descriptor and data structure parm with nulls
Hi,
I am using operational descriptors (opdesc) for check data structure
data
length in subprocedure. This technique works quite well with standard
with
structures. But when the data structure is specified with nulls the
descriptor is not passed to the subprocedure.
for example, when I use the CEEGSI API to get operational descriptor
information I receive the error message CEE0502.
The source code
D FACEMI_alias_t...
D E DS extname(FACEMI) alias
D qualified template
P initialize...
P B export
D PI opdesc
D r likeds(FACEMI_alias_t)
D options(*NULLIND)
D type S 10I 0
D len S 10I 0
D size S 10I 0
CEEGSI(%parmnum(r): type: len: size: *OMIT);
r5_assert(size = %size(FACEMI_alias_t): LEVEL_ERROR);
Is it possible to pass the operational descriptor for a data structure
related
nulls?
Thanks,
Javier Mora
