/* EX_HELLO.C - Example of a trivial OpenDoors program. Demonstrates */
/* just how simple a fully functional door program can be. Also */
/* shows all the basic elements required by any program using */
/* OpenDoors. See manual for instructions on how to compile */
/* this program. */
/* */
/* This program shows how to do the following: */
/* */
/* - #include the OpenDoors header file, opendoor.h. */
/* - Create a mainline function that can be compiled under */
/* both DOS and Windows versions of OpenDoors. */
/* - How to display text on multiple lines. */
/* - How to wait for a single key to be pressed. */
/* - How to properly exit a program that uses OpenDoors. */
/* The opendoor.h file must be included by any program using OpenDoors. */
#include "opendoor.h"
/* The main() or WinMain() function: program execution begins here. */
