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.
