You have not followed the installation instructions correctly to set
up your environment properly to allow you to run DJGPP programs: see
http://www.delorie.com/djgpp/v2faq/faq1.html
 
You have to put a line like the following in CONFIG.SYS, AUTOEXEC.BAT,
or say, for example, DJGPP.BAT (which you then have to run before
using any DJGPP programs):

	SET DJGPP=c:\djgpp\djgpp.env

where c:\djgpp is the directory where you installed DJGPP and which
contains the djgpp.env file. You can find this out from a DOS command
prompt window by typing the command:

	dir /s c:\djgpp.env

and it will eventually produce output like:

	Volume in drive C is DISK
	Volume Serial Number is 1234-5678

	Directory of C:\djgpp

	DJGPP    ENV         3,599  02-24-04 11:54p djgpp.env
	         1 file(s)          3,599 bytes

The directory name you need is on the third non-blank line.

It's not your program, it's your configuration setup.
