Editing BBC BASIC (section)

===Acorn's involvement===
Acorn first developed System BASIC and [[Atom BASIC]] for their early [[6502]] microprocessor computers<ref>{{cite web |author1=Ian Sinclair |title=Atomic Research |url=https://www.flaxcottage.com/ComputingToday/8104.pdf |publisher=Computing Today |access-date=21 January 2024 |pages=21–24 |date=April 1981}}</ref> that were sold to kit-build customers. With the development of the Proton as a [[Front-end processor]], Acorn were designing for more powerful computing.

In order to produce a computer to satisfy the BBC specification, the Proton became the BBC Microcomputer, usable as a stand alone computer. By retaining the capability to be connected to a [[Z80]] computer, Acorn was able to comply with the requirement of a computer supporting [[CP/M]].<ref>{{cite web |title=BBC Micro ignites memories of revolution |url=http://news.bbc.co.uk/1/hi/technology/7307636.stm |publisher=BBC News |access-date=21 January 2024 |date=21 March 2008}}</ref>

[[Sophie Wilson]] developed the implementations of BASIC at Acorn.<ref name=":0">{{Cite web |last=Purdy |first=Kevin |date=2023-11-29 |title=BBC BASIC remains a remarkable learning tool, and now it's available everywhere |url=https://arstechnica.com/gadgets/2023/11/bbc-basic-keeps-evolving-and-now-you-can-run-it-on-nearly-any-platform/ |access-date=2024-08-05 |website=Ars Technica |language=en-us}}</ref> The dialect on the BBC Microcomputer became compatible with Microsoft BASIC and so was acceptable to the BBC. It already had features from the ALGOL 60 group of computer languages that Wilson added to enable some structured programming methodology to be used.
