	HELP information may be requested either by typing
 
		HELP qualifier1 qualifier2 qualifier3    ...
	or
		HELP $TOPIC qualifier1 qualifier2 qualifier3....
 
		The $TOPIC form should be used if the HELP qualifier1
		instructions say to do so.  Only the first 3 letters
		of any qualifier need be typed.  Also leading / marks are
		ignored.  Hence  HELP SET BUF and HELP SET /BUF
		are treated identically.  The order of qualifiers is  
		important and any secondary, etc. qualifiers are described
		by typing HELP qualifier1.  Valid qulaifiers may be found
		by typing   HELP INDEX.
