    Freebasic Beginners Guide

    An updated Beginners guide to FreeBASIC

    The purpose of this project is to create and update a beginners guide to FreeBASIC. Over the years I have noticed that there was only three real ways to learn FreeBASIC. The FreeBASIC Documentation, the FreeBASIC Community Forum, and A old beginners guide written by Richard D. Clark and Ebben Feagan. Each of these sources are great, but they all assume some experience with a programming language. This Project is taking Richard D. Clark's and Ebben Feagan's "A Beginner's Guide to FreeBasic" and is editing, updating, reorganizing, and simplifying this guide. Mr. Clark and Mr. Feagan generously open sourced there guide so I could start this project. Without being able to stand on their shoulders I could not have even started this project. Please check out my homepage for updated information and ways you can help with this ongoing project. If you can please buy me a hamburger as it is hard writing a book.
