FOCAL, which is allegedly short for "Formulating On-line Calculations in Algebraic Language", is an imperative, interpreted programming language similar to JOSS. It was first introduced in 1968, and FOCAL-69 was widely used on the PDP-8 minicomputer from Digital Equipment Corporation.
FOCAL (which either stands for '''Fo'''rmula '''Cal'''culator or '''F'''ormulating '''O'''n-line '''C'''alculations in '''A'''lgebraic '''L'''anguage), is an imperative, interpreted programming language similar to JOSS.

Like JOSS and BASIC, FOCAL was not intended to be used for developing large applications; the manual said it was "designed to help scientists, engineers, and students solve numerical problems." The design goals thus emphasize simplicity and accessibility.
