Synopsis

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. BBC BASIC is a programming language, developed in 1981 as a native programming language for the MOS Technology 6502 based Acorn BBC Micro home/personal computer, mainly by Sophie Wilson. It is a version of the BASIC programming language adapted for a U.K. computer literacy project of the BBC. BBC BASIC, based on the older Atom BASIC (for the Acorn Atom), extended traditional BASIC with named procedures and functions, REPEAT-UNTIL loops, and IF-THEN-ELSE structures inspired by COMAL. The interpreter also included powerful statements for controlling the BBC Micro's four-channel sound output and its high-resolution graphics display. One of the unique features of BBC BASIC was the presence of an inline assembler allowing users to write 6502 assembly language programs. The assembler was fully integrated into the BASIC interpreter and shared variables with it. This allowed developers to write not just assembly language code, but also BASIC code to emit assembly language, making it possible to use code generation techniques and even write simple compilers in BASIC.
