Re: Operational descriptor and data structure parm with nulls

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 descriptor
is created. The compiler may not be able to build an operational descriptor
of a data structure with nulls.

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 also
includes the OPDESC keyword.

Subject: Operational descriptor and data structure parm with nulls


Hi,



I am using operational descriptors (opdesc) for check data structure parm

length in subprocedure. This technique works quite well with standard data

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 with

nulls?



Thanks,



Javier Mora
