## Parameter.Default

### Introduced

v3.0

### Description

Returns the default value (Variant) of the parameter. Some parameters have a default value, which defines what the initial value of the parameter is.

### C# Syntax

    // get accessor
    Object rtn = Parameter.Default;

### Examples

#### VBScript Example
