I havent used that compiler yet BUT i think i know whats wrong, first of 
all, in most cmopilers main() defualts to  int main(void) So by just 
having the line main() chances are your compiler reads it as int main 
(void)  SO first off i would add the line  return 0;  to the end of your 
file.... Copy this code and try to compile it....first...

#include <iostream.h>

int main(void)
{
	cout << " Hello, World\n";

	return 0;
}

If you get an undefined COUT when you compile... check the file 
extention and see if its   .cpp OR .c or .gxx or .c for unix. Djgpp if i 
remember correctly is a c/c++ compiler so there verywell could me a 
option to have it use either the .c or .cpp nameing system some 
compilers like borland will automaticly figure it out for ya, but some 
of the older version don't... if the above program doesnt work, and you 
copy it excatly, then the problem lies in an internal switch that you 
must change... < in borland if you have the nameings set wrong it will 
POP you into the iostream.h file and you will be wondering <THere isnt 
anything wrong> but that is what it is.... =) anyhow good luck with 
it.... and take care....
