### Examples

#### VBScript Example

    '
    '       This example demonstrates how to create a single proxy parameter (by specifying
    '       a single parameter as the master) or multiple proxy parameters with the same
    '       prefix (by specifying an entire property set as the master).
    '
    set oNull = GetPrim( "Null" )
    AddProp "Custom_parameter_list", , , "CustomPSet"
    ' Specify a specific parameter
    AddProxyParam oNull & ".CustomPSet", "Camera_Root.kine.local.posx"
    ' Add proxy parameters for each parameter of the light.visibility property
    AddProxyParam oNull & ".CustomPSet", "light.visibility", "prxy"
    ' When you inspect the new property set, you can see a flat list of parameters. All
    ' names except on the first parameter begin with "prxy_". Eg., 'prxy_viewvis'
    InspectObj oNull & ".CustomPSet"
