[Deskin, Bob]

Okay. I'll think on this one. As usual, no promises.

	That's a great suggestion. I've had to modify the PATH and FIND
procedure several times for just such cases.

		Interesting idea. Can I get a feel from the list as to
how often people modify the PATH procedure? And would something like
this reduce that need? Why else do you write your own PATH procedures?
		 
		We generate the PATH and FIND based on ACCESS statements
(specified or implied) for the PRIMARY file. The two procedures are tied
together. The generation is fairly basic at this point.

			Here is a new enhancement targeted at reducing
the number of times a programmer has to hard code the PATH procedure.
			 
			FILE Users PRIMARY
			  ACCESS VIA UserId &
			       USING T-UserId &
			          IF T-UserId NE " "
			  ACCESS VIA UserId &
			       USING UserId &
			     REQUEST UserId
			  ACCESS SEQUENTIAL
			 
			 
			This new feature would generate a PATH statement
similar to the following thus removing the requirement of hard coding
the PATH every time we want to "override" the default path because of
passed-in values or re-finding based on a temporary item. etc.
			 
			PROCEDURE PATH
			BEGIN
			  IF T-UserId NE " "
			     THEN LET PATH = 1
			  IF PATH = 0
			     THEN PROMPT T-UserId
			...
			END
