+**
+**    added getxkey(), which can read extended keystrokes that start with
+**    0xE0, as well as those which start with 0x00
+**    
+**    added global char ScreenAttrib, the attribute used by ScreenClear():
+**    it defaults to 0x07 so as not to break existing code.
+**
+**    added ScreenMode(), to return the current video mode
