Easy Forth (2015)
This small ebook is here to teach you a programming language called Forth. Forth is a language unlike most others. It’s not functional or object oriented, it doesn’t have type-checking, and it basically has zero syntax. It was written in the 70s, but is still used today for certain applications .
