RE: Operational descriptor and data structure parm with nulls

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
