Re[4]: how to add 10,000 records to new file with one fi

     Catch 22. Insert before triggers cannot determine the rrn of the 
     record until DB2 adds it to the file. New records are NOT always 
     added to the end of the file (re-use deleted records), so you 
     cannot assume that new_rrn=Current#records+1. 
     
     I think this whole approach is too prone to problems to make it 
     usable. The whole point of relational databases is to present your 
     data logically. Why would you need to artificailly tie the data to 
     its rrn in the file? Seems there are too many ways to mess it up.

Actually the trigger has to be *before *insert if you want to change the 
value of a field and the allow repeated change has to be *yes.
