• Subject: Null Capable Fields... Help Needed...

We have this scenario here at work.  And I thought I ran it by you to see if
anybody has any ideas.

We have fields within DB2 files defined as "Null Capable".

Within an RPG IV program we try to define fields using the "like" keyword over
these null capable fields, or define fields using externally described data
structures over the file with null capable fields.
However, none of these fields defined internally to the RPG program keep the
null capable attribute.
i.e.   I cannot use the %NULLIND BIF on the field.

Here is a excerpt from the on-line AS/400 reference books (V4R4) on this
"If the file used for an externally described data structure has null-capable
fields defined, the null attribute is not used in defining the RPG subfield."

Is there a way to define fields internal to RPG programs as null capable?
If not, is there a work around for this?
