new feature request - user defined functions

[Joe Boyle]

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.

    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.
