Borland C++ MSDOS utility program reports the key code generated when you press a key

/*	keycodes.cpp			3-10-96
	Copyright (C)1996, 2006 Steven Whitney.
	Published under GNU GPL (General Public License) Version 3, with ABSOLUTELY NO WARRANTY.

	Borland C++ 4.0 for MSDOS.
	Shows values from keyboard keystrokes.
	A run of the program shows that getch() does not interpret function
	keys, nor even acknowledge them as keystrokes. Neither does kbhit().

	To use function, altkeys, etc., use ci(), which now handles them all
	correctly.  AND use csts() instead of kbhit().
