Using Parameters in Functions
To use input parameters in a user-defined function, first add the parameters.
After you create input parameters, you can edit, move, or delete the parameters.
The following pages describe the function parameter management tasks:
- Adding Function Parameters
 - Editing a Function Parameter
 - Moving a Function Parameter
 - Deleting a Function Parameter
 
To use an input parameter in a user-defined function, select the parameter to add it to the expression, as described in Creating a Function.
