You are running under the windows OS. This OS is NOT the DOS
operating system that was discontinued more than 10 years ago.
This program is writing to a specific address. This will never work
under the win32 versions of windows (windows 95 or higher).
But all this is probably too technical for you. The fact that you
attempt to compile this under windows shows that you haven't got
any idea what this code is doing. I would suggest that you find
someone competent and give this to him (her).
Under DOS, you could write to any memory address since the OS
wasn't using protected mode and virtual memory. This doesn't work
since windows 95...
Anyway, maybe it will run if you compile it under a 16 bit DOS compiler
under the emulation layer of windows, who knows.
