Tiny BASIC

Tiny BASIC is a deliberately small dialect of the BASIC programming language, created in 1975 by Dennis Allison. Its defining aim was to fit into as little as two or three kilobytes of memory, which made it valuable on the first hobbyist microcomputers of the mid-1970s, when typical machines had only four to eight kilobytes of memory. To meet those limits the language was cut back sharply: arithmetic was purely integer based and it had no arrays. Its statements are the core of classic BASIC: PRINT, IF with THEN, GOTO, INPUT, LET, GOSUB and RETURN, plus CLEAR, LIST, RUN and END, with single-letter variables from A to Z. The Programming Language Database lists it alongside Dartmouth BASIC, Microsoft BASIC and the implementer Li-Chen Wang as related entries, and it is held here as one of the small, early members of the BASIC family.
