Not afraid of, but to be careful when writing. I have had trouble with
my triggers, because I left thisthat out. As for timestamping,

added columns.
Is there a command that says ³update the time stamp if and only if there

Okay, color me confused, but what exactly are you wanting to do anyway?
I am writing a type of message stack that is built while a task is
processing and presented to the user at the end of processing. I do it
using a function like
Logit(Blah, blah, blah);
Which records the SessionID, Sequence and Message, which is presented to
the user in sequence at the end
