/* FUNKEY.C - a program for redefining fyunction keys */
/* */
/* Copyright (C) 1983 Kenneth C. Wood */
/* */
/* From PC Magazine - - June 1983 Page 424 */
/* */
/* Works with IBM PC-DOS 2.0 - to use it, have on your */
/* system disk the files: */
/* ANSI.SYS - supplied with DOS */
/* CONFIG.SYS - file with the line "device = ansi.sys" in it */
/* and one or more files with the extension .KEY i.e. */
/* WORDSTAR.KEY, MYOWN.KEY, FUNKEY.KEY, or */
/* DOS.KEY - supplied by you and containing */
/* your chosen new key definitions, and of course */
/* FUNKEY.EXE - the compiled and linked FUNKEY.C */
/* */
/* Now when the system is booted, the ANSI terminal */
/* emulator device driver will be installed, giving */
/* you the capability to do marvelous things, including */
/* redefine the function keys by issuing the command: */
/* FUNKEY MYOWN.KEY */
#define SEQ "\033[0;" /* Initial sequence to ANSI driver */
#include "stdio.h" /* Copy in the standard I/O routines */
