       [<cColor>]      , ;  // Default: SetColor()
       [<nCursor>]       ;  // Default: SetCursor()
     ) --> nWindowID
Description

If the optional parameter <lClearScreen> is set .T. (true) the screen area for the window is cleared before the window is opened.

With <cColor> and <nCursor> an individual cursor shape and window color can be specified for the new window.

NOTE

Before WOpen() may be called the function WInit() must be called in order to initialize the text mode window system. Otherwise a runtime error is created.
