HFL and HDX:  A new means of finding out what HELP is available through the
  system HELP command.  
Usage:	HDX MCR|DCL [qual1 [qual2 ...qual9]] [>outputfilespec]
	HFL MCR|DCL [qual1 [qual2 ...qual9]] 
	
 1.0  HFL - Help File Level display
	 HFL shows what  all the major qualifiers are on a given HELP topic.
	 Examples: HFL DCL shows all level 1 topics under DCL; HFL MCR BRU
	 shows all second level qualifiers under BRU. Display on TI: only,
	 formatted as many per line as possible. TECO macro, may seem slow.

 2.0  HDX -- Help File Index command (runs very fast!)
         HDX is used like HFL, by typing "HDX  MCR|DCL  qualifier  ...".   It
         differs in that it does not stop at the one level;  if you type "HDX
         DCL SET", for example , HDX will list out every sub-qualifier  under
         the  SET  command, from level 2 on down as far as the help files go.
         (This alone takes several pages on your terminal -- be  prepared  to
         use NO SCROLL.) Can redirect output to a file or terminal by 
	 appending ">filespec" or ">LP0:" to the command line. Written in C.

         If you try "HDX DCL" you will be shown the qualifiers for everything
         (!) under DCL.  Beware:  this can take several minutes!
