Re: Data base triggers

Absolutely Nelson. Thanks for saying that so kindly.  I even went back and 
looked at my sent mail because I can't believe I typed "*NO".  It took a 
long time to learn about that parm.  Pete Hall finally set me straight on 
it a couple of years ago. 

I will admit to not understanding it though.  Since we are only changing 
the buffer and not the record why does the database care? And why not just 
always set the parm at *YES?  What is the downside?  What protection or 
efficiency does it provide?

All except the first one.  I'm sure Booth meant to say *YES.
