Talking about V4.4 RPGIV:
The support is very manual, you have to test or set the
null indicator with the bif %NULLIND. If you need to work
with null capable fields otherwise, don't do anything.
The real problem is passing fields as parameters
(prototyped or not) to other programs since the support of
null capable fileds is only for database fields. I mean you
cannot declare a field in D-spec as null capable neither
you can define a DS from a PF expecting to get null capable
fileds in the DS even if the original PF had null capable
fileds.
By the way how do you test if a field resulting from an
embebbed sql statement is null? I don't know how to handle
since is not the same as RPGIV. Somebody know other ways?
