/*****************************************************************
*
*   Keyboard Handling
*
*   This program demonstrates separate compilation by splitting
*   the program KEY into two parts: the main program, and a
*   separately compiled file with the keyboard subroutines that
*   can then be called from many different programs without the
*   need for recompiling.  See KEY.CC for a full description of
*   what this program does.
*
*   The program now consists of four files:
*
*        Key2.Build - EXEC file which separately compiles the two
*                     source files, then links their object
*                     modules to create the final program.  To
*                     use the EXEC file, simply type KEY2.BUILD
*                     from the command line.
*
*        Key2.cc    - File containing main program.
*
*        Key2.h     - Header file accessed by the main program;
*                     Contains declarations of external functions.
*
*        Key2.Funcs - File containing keyboard functions called
*                     by main program.
*
*   See Key3 for a version that uses assembly language to read
*   the keyboard.
