WCLOSE()
 Closes the active window
------------------------------------------------------------------------------
 Syntax

     WCLOSE() --> nWindow

 Returns

     WCLOSE() returns the window handle that will subsequently become active.

 Description

     This function closes the currently selected window.  Control is returned
     automatically to the window with the highest handle or number.

 Notes

     .  The window handle closed with WCLOSE() is subsequently
        available again and can be reused with the next WOPEN()

     .  If the physical screen (Window 0) was active prior to the
        window closure with WCLOSE(), then Window 0 is skipped over and the
        window that was active before the WCLOSE() is selected.

 Example

     After this command sequence you are in window 3, not window 2:

     WSELECT(3)
     WSELECT(2)
     WSELECT(5)
     WCLOSE()
