* This file contains the main driving routine, and some keyboard processing
* code, for the MicroEMACS screen editor.
*
* REVISION HISTORY:
*
* 1.0 Steve Wilhite, 30-Nov-85
* - Removed the old LK201 and VT100 logic. Added code to support the
* DEC Rainbow keyboard (which is a LK201 layout) using the the Level
* 1 Console In ROM INT. See "rainbow.h" for the function key definitions.
*
* 2.0 George Jones, 12-Dec-85
* - Ported to Amiga.
*
* Later versions - Walter Bright, Bjorn Benson
* - Ported to linux
* - Ported to Win32 (compile with Digital Mars C compiler, www.digitalmars.com)
* - Ported to DOS32
