| Name | Description |
|---|---|
| Required | The parameter is mandatory. A missing parameter results in a user warning dialog. |
| Optional | The parameter is not required. If it is missing, the function still compiles and evaluates. Note that optional parameters should come after all required parameters. |
| OptionalUnlimited | Any number of parameters which are not required. Note that the total number of parameters should not exceed 255 and the optional unlimited parameter should be the final parameter. |
Remarks
Specify the parameter attribute for the ParameterInfo objects in the IFunction.Parameters array to create a function signature. A function signature provides parameter validation when a function is evaluated.
