Name

Specify the name of the variable. When the X-Function is executed by script, you have to assign values to variables using their names. Therefore, we recommend that you use shorter names and begin them with different characters.

Label

Specify a label for the variable. Special characters and white space are allowed.

Input/Output

Specify whether the variable is used for input, output or both.

Data Type

Specify the variable data type.

Data

Specify the default value for the variable.

Control

Specify the control for the variable in the dialog box (combo box, slider, etc.).

Option String

Specify an option string for the variable. You can apply advanced settings with option strings, such as grouping several variables together, enabling recalculation, etc. More details can be refered to X-Function Programming CHM.
