RE: Programming a trigger audit in ILE

["Tracy Ball" <TBall@xxxxxxxxxxxxxxxx>]

Don't break your arm patting yourself on the back!   I never said I didn't 
understand the code, I just said eventually something I did fixed the program 
and I really didn't get to take the time to really figure out which change 
corrected the problem.

In any case , thank you for the input, it is always helpful.

That technique works.  You do not need pointers to use offsets.  You can
describe the record as a giant array and use an array index as the offset.
Or you can go nuts and use substring.  The idea is the same: use the
"offset" values given in the trigger buffer to locate the record, and DON'T
ASSUME that the record data always starts in the same place in the trigger
buffer.

Sounds like you are looking at less than stellar examples.

In my case, never.  If I don't understand the code then I don't put it into
production.
