Hans 
After I sent that a I had another question.  The trigger thing. 
I'm mirroring 6 AS/400's  back to a central AS/400.  Using DB triggers
on the Plant boxes that feed an APPC program that sends the record to Corp.  
On the Corp. AS/400 the APPC program puts the records away (Update/Add 
RPG program)to the data base based on the trigger event.  How would
I write those fields which have the Null Flag set to YES (on a V3R2 CISC 
box using RPGIV)?

I guess I'm lucky I'm not using Nulls yet huh?
