Candi, most cameras do have a macro option. In all the point and shoots that I've used, the icon on the dial always looks like a Tulip. Sometimes there's actually an option on the dial, but if you're using a super small camera that doesn't have the different modes on the dial, you may have to go into setup on your camera to choose it.
Hope that helps!
And, I have to second the photography course - of course, that's a bit of self-promotion there, since I'm the instructor!
