Crystal Reports for Eclipse Designer Guide

Calling a custom function from within a formula

Custom functions can be selected for use in formulas just as you'd select any other function. They can be used in any formula in your report, including report formulas, formatting formulas, record selection formulas, and so on. A formula can call any custom function, even if the custom function was written in a different syntax.
Once you've selected a custom function for use in your formula, you must specify the argument values as defined when the custom function was created.
