new feature request - user defined functions

[Deskin, Bob]

I do see the value of some form of user defined function as part of an
expression so I'm not debating that. All I'm saying is that you can do
something like that in QUICK already via the DO EXTERNAL. Maybe not as
convenient, but in most cases it can get the job done.
 
As for two versions of QUIZ, it's a question of what sort of access the
user has. Others have pointed out that you can already access stored
procedures so restricting access to a user-written function is a little
late. Point taken.

	i think that a define is'nt actually asigned a value until it is
referenced,
	 
	define mydefine = 'item returned from do ext' ;...( defined item
mydefine contains nothing )
	 
	if mydefine = .... ( defined item mydefine now contains value in
'item returned from do ext' )

		Bob,
		 
		The problem with Quick's DO EXTERNAL is that you have to
call it within a procedure. What if you need to load a define with the
data returned from an external routine?
		 
		Why would you need two versions of Quiz?

		QUICK can access any library via DO EXTERNAL. It's a lot
easier to do that than to force a specific format on the developer. As
well, external calls are different on each platform and with DO
EXTERNAL, you can have a generic format or close if you care.
		 
		As for QUIZ, we've always been torn because of QUIZ's
nature as a read-only product plus the fact that it is often used by end
users. We'd have to provide two versions, one with and one without.
		 
		Bob

			Allow Quick, Quiz and Qtp to call a user defined
function that is defined within a library.
			 
			An example of it's use would be for check digit
calculation/validation and encryption/decryption routines. Both here and
at previous sites I implemented the code in USE files. This was fine
with the check digit routines but not the encryption routines as the
encryption method and key(s) were easily seen (we had to roll our own
encryption routines as the auditors were after something stronger).
			 
			This feature would also enable the developer to
include the mathematical functions (sin, cos, tan, etc.) that have not
been implemented in PowerHouse.
