Problems using camera

Question

Recently I came across a Nikon N 2000 camera with a self focusing 35mm Macro lense. I was told all I had to do was put the f stop at f 22 point and shoot. This is confusing to me as I did not get a manual for the camera, so I can not look up any information as how to use the camera. I do not have the confidence in myself just to point and shoot as i have always had a camera that i had to focuse first. I do not wish to waste film, it is a nice heavy camera and would like to use it for Macro picrure taking. Can you please help me?

Thank you
Tom
