Can you create a function parameter? 1

[-cush-]

Is there a way to create a function with input parameters? I'm not talking about parameter fields. I'm talking about being able to call a user defined function from within another function, and send it parameters.

ie create a function called max(a,b) that would return a number of which ever parameter is bigger, a or b.

Depends on your version/edition of Crystal, please post technical information when requesting it.

You can create a UFL:

A simple generic means would be to assign the 2 fields/values to formulas, and then create an IF statement to return the larger.

Thanks!

The max function was just an example, but now that I know how, I will be creating my own function library.
