RE: Programming a trigger audit in ILE

["Tracy Ball" <TBall@xxxxxxxxxxxxxxxx>]

Jon,

I am having trouble defining the Null Maps.  The compiler doesn't like the 
ONField and NNField definitions.  I am a little lost how this would be used 
anyway.  My file contains a date field that could be '0001-01-01'.  Is that 
considered a null value for an *ISO date?   If I am not doing anything specific 
with a field, do I need to code for the null maps?

null map and the new record field.

The fact that you are talking about adding extra fields indicates that you
are not using the correct technique for this.  You should really be using
the offset entries and pointers to make it work simply and cleanly.

Check out the article "Are you trigger happy" which you can reference from
the page www.partner400.com/ArticlesEXTRA1.htm it explains why the
techniques sometimes used prior to V5R1 will only work in 1 out of 16 cases,
and gives you a basic structure for how you should approach the problem.
e-mail me off line if you have any problems with it.
