Sorry if my attitude appeared snarly. I got the impression that you were
snarly at IBM for not documenting it. I was just pointing out that they
had.

Subject: RE: Programming a trigger audit in ILE
I am not sure I like the "connotation" of your reply. IBM may have,
however, this is my first trigger program, and I most certainly did NOT
ask this question without spending some considerate time researching and
downloading examples. I really could have figured this out on my own,
however, this forum did save me quite a bit of time in doing that (and I
would hope that is one of many primary functions of this group).

Actually IBM documented the snot out of the change in the 'Memo to users'
and a few other places.

Subject: RE: Programming a trigger audit in ILE
I knew everyone would state to use the offsets, as that is why I even
stated in my previous message that , that is the route I would go.
However, as I have always done, I want to know why I had to add the extra
buffer field when it wasn't in any documentation? I mean, if the offsets
are the only way to go, then why don't the buffer example just have one
big field that contains the old/new record values and tell you to use the
offsets to determine the starting and ending points, rather than show
individual fields?
I am going to use the offsets, but it still "bothers" me that I had to do
that and I don't know why. The other thing I left out is that the second
parm length said the first parm was 288 characters when I only came up
with 266.
Thanks for the input, as I know I have more work to do. I was just curious
if there was an actual reason why I needed to input the extra field when
it wasn't illustrated in any documented examples.
How many times have we fixed a program, and then not really understood why
or how we fixed it??

Tracy,
In the data structure that's passed to your trigger program there's
some fields that give you offset of where the record, null maps, etc
are located in memory.
You need to use those numbers to locate the data.
If you use something like a "filler field" what will happen if they pass
you a different number on the next call? Or maybe on the next release
of OS/400?
I posted a (really old and somewhat outdated) example of this type
of code here:
http://archive.midrange.com/rpg400-l/199908/msg00110.html
Keep in mind that in newer releases of OS/400 you can eliminate the
awkward array logic and replace it with pointer arithmetic... but
this code will still work.
