UFL

Delphi 5 and Crystal Reports 8.5 and User Function Library

Hello all,    I am trying to create a UFL in Delphi 5 for use in Crystal Reports 8.5.  Does anyone know how to successfully do this?  I have some examples, but they all leave out some information and I end up not being able to create the UFL and use it the way it is supposed to work. Thanks,...
