    CreatePrim "Grid", "MeshSurface"

    SetSelFilter "Vertex"

    SelectGeometryComponents "grid.pnt[0,40]"

    logmessage "is point #0 a boundary ? " _

    	& selection(0).SubComponent.ComponentCollection(0).IsBoundary

    logmessage "is point #40 a boundary ? " _

    	& selection(0).SubComponent.ComponentCollection(1).IsBoundary

    ' Expected result:

    'INFO : is point #0 a boundary ? True

    'INFO : is point #40 a boundary ? False

#### 2. JScript Example

    NewScene( null, false );

    CreatePrim("Grid", "MeshSurface", null, null);

    SetSelFilter( "Vertex" );

    SelectGeometryComponents( "grid.pnt[0,40]" );

    logmessage( "is point #0 a boundary ? "

    	+ selection(0).SubComponent.ComponentCollection(0).IsBoundary );

    logmessage( "is point #40 a boundary ? "

    	+ selection(0).SubComponent.ComponentCollection(1).IsBoundary );

    // Expected result:

    //INFO : is point #0 a boundary ? true

    //INFO : is point #40 a boundary ? false
