     Yes, the trigger executes before any database validation rules are 
     checked.

Quick question,
     
Can you use a "before" trigger to generate the key value of a file?
     
In other words, say an sql statement does an "insert" into a uniquely 
keyed file, with the key field of zero.  The trigger program then gets 
the next available key field number and updates the "out" buffer with 
it.
     
Thanks in advance,
     
Rick
