  43 /*  FUNCTION
  44     Changes the current window and/or the screen title.
  45
  46     INPUTS
  47     window - Change the title for this window or the screen which the
  48         window contains.
  49     windowTitle - New title for the window or ((UBYTE *)~0L) to keep the
  50         old title or NULL for no title. If you specify a string,
  51         this string is *NOT* copied.
  52     screenTitle - New title for the screen of the window or ((UBYTE *)~0L)
  53         to keep the old title or NULL for no title. If you specify
  54         a title for the screen, this title will be shown when the
  55         window becomes active. If you specify a string, this string
  56         is *NOT* copied.
  57
  58     RESULT
  59     None.
  60
  61     NOTES
  62     You should be careful with specifying a screen title because that
  63     may irritate the user.
