   Liz, you have gone far beyond what I would expect and I sincerely   
   appreciate it. Your assumption about stripping out CRLF and Tabs is   
   correct. Your code is straight forward and I understand what each line   
   is doing.   
      
   But, my problem is when I try to read the help tutorial, I can't even   
   find WHERE to put your code, or if it gets attached to an object, etc.   
   In other words, it is like trying to learn to drive a car, and the   
   instructions have omitted how to first shift into gear. I have always   
   learned by example. But the Paradox tutorial assumes too much, IMO,   
   and does not begin with the basics. I am sure I could learn how to   
   program in OPAL if I could just get over that first hump. I know there   
   are many things I would like to be able to do in OPAL. I have searched   
   for some kind of tutorial book, but have never found anything useful.   
      
   I certainly do not expect someone from this forum to teach me. What I   
   really need is a reference other than Paradox's help files.   
      
   Thank you again,   
   -Ike
