The modularization: LoadScript()

Window.LoadScript(filename):

You can replace the current script code.

Here's an example: 
// File: loadscript.w_js (JScript)

Window.width = 40 * Window.cxChar;
Window.height = 8 * Window.cyChar;

Window.AppendMenu(0,"MF_STRING",8000,"Next Script");
Window.DrawMenuBar();

function WM_COMMAND(id)
{
 if (id == 8000) Window.LoadScript("timer.w_js");
}

'VBScript
Window.width = 40 * Window.cxChar
Window.height = 8 * Window.cyChar

Window.AppendMenu 0,"MF_STRING",8000,"Next Script"
Window.DrawMenuBar

Function WM_COMMAND(id)
 If (id = 8000) Then
     Window.LoadScript("timer.w_js")
 End If
End Function
Notes:
  1. The current menu shall delete.
  2. The controls layer and graphics layer shall not delete.
