These are functions that are in User
Function Libraries or UFLs. A UFL is a separate dynamic link library or
Automation server that you create and that
Crystal Reports can use to add your own customized functions
to the formula language. Writing a UFL is more involved than writing a formula
using Crystal syntax. See
Crystal Reports Developer's Help for details.
Note: Using UFLs makes your
reports less portable because you must distribute your UFL along with the
report.
