Applesoft BASIC

The Applesoft BASIC is a dialect of Microsoft BASIC developed by Marc McDonald and Ric Weiland in 1977, especially for Apple II computers. Applesoft BASIC was supplied by Microsoft and its name is derived from the names of both Apple and Microsoft. Apple employees, including Randy Wigginton, adapted Microsoft’s interpreter for the Apple II and added several features. It happened because, when Steve Wozniak wrote Integer BASIC for the Apple II, he did not implement support for floating-point math because he was primarily interested in writing games, a task for which integers alone were sufficient.

It supersedes Apple Integer BASIC and is the BASIC in ROM in all Apple II series computers after the original Apple II model. It is also referred to as FP BASIC (from “floating-point”) because of the Apple DOS command used to invoke it, instead of INT for Integer BASIC.

The first version of Applesoft BASIC was released in 1977 on cassette tape and lacked proper support for high-resolution graphics. Applesoft II, which was made available on cassette and disk and in the ROM of the Apple II Plus and subsequent models, was released in 1978. It is this latter version, which has some syntax differences and support for the Apple II high-resolution graphics modes, that is usually synonymous with the term “Applesoft“.

Today Applesoft BASIC is 44 years old!
