Re: Trigger question

And now you know why the offset didn't automatically do the add 1 like you 
did with the substring.  :-)

Re: Trigger question






I'm sorry, I left that out.  I had the buffer redefined as an array.  I
modified the code to your method Rob and it actually looks like this,
because of pointer math vs. index.

D OUTDS    E DS                  ExtName(XXX)  Based(TbAftPtr)
     TbAftPtr = %addr(parm1) + NewOff;

Thanks,
