   Try implementing one, especially with a reasonably sized grammar, and   
   you will very rapidly understand that it is not as simple as you seem   
   to think it is. :-)

   As I mentioned above, this is no longer about DCL. I picked the above   
   standalone example, a LL(1) RD parser, because it's a really good example   
   of the different scale of effort involved in writing it in Macro-32   
   instead of in C.
