Passing parameters to a CGI

Hi!! I'm programming a CGi in C (DOS) and I'm trying to pass a parameter to it. I have to pass only 1 parameter.. if this is 1, the program makes an action, if it's 2, another and it it's 3, another. I'm trying for example: zzzz.exe?1, but when I tested the program printing argc variable, it prints a 3, and printing strings stored at argv, I couldn't get any paramater.... how can I do it?

Thanks in advance,
Jaime

Well, don't take it as an offence, but all you can do is studying CGI :)

A CGI program gets parameters from environment variables or from the standard input stream, depending on the FORM METHOD (GET or POST respectively).

Cheers.
