I take it that the numbers in the front are _NOT_ part of the C program ?
otherwise, you'll be in for a lot of trouble.

You should do this in 2 steps. First check that the DJGPP compiler is
installed properly, then try to use tools like RHIDE.

If you followed the installation instructions,
you should be able to compile the program (in a DOS box) using

gcc 02L01.c

(at least, if that is the name of the program).
As result, you should get a file aout.exe
If not, post what the compiler is spitting to you, so we can see what
goes wrong.

There are a couple of nice options, which make living a lot easier, but
that is not the problem at this moment.

Actually, it is _NOT_ ANSI C, but the compiler should be able to swallow it.

(In ANSI, the code would look as follows:

/*02L01.c : This is my first C program. */
#include <stdio.h>

int main (void)
{
    printf ("Howdy, neighbor! This is my first C program. \n");
    return 0;
}

(note the use of 'int' and '(void)' in the definition of main)
For some reason, books never do this correctly... :-(
