The Bourne shell, or sh, was the default Unix shell of Unix Version 7 and most Unix-like systems continue to have /bin/sh - which will be the Bourne shell, or a symbolic link or hard link to a compatible shell - even when more modern shells are used by most users.

Commodore BASIC, also known as PET BASIC, is the dialect of the BASIC programming language used in Commodore International's 8-bit home computer line, stretching from the PET of 1977 to the C128 of 1985. The core was based on 6502 Microsoft BASIC, and as such it shares most of the core code with other 6502 BASICs of the time, such as Applesoft BASIC.

S is a statistical programming language developed primarily by John Chambers and (in earlier versions) Rick Becker and Allan Wilks of Bell Laboratories. The aim of the language, as expressed by John Chambers, is "to turn ideas into software, quickly and faithfully."

SAM76 is a macro programming language used from the late 1970s to the present 2007 initially ran on CP/M. The SAM76 language is a list and string processor designed for interactive and user-directed applications, including artificial intelligence programming, and permits high portability from machine to machine. The language shares certain features in common with LISP, Forth, and shell programming languages of the UNIX operating system. Claude A. R. Kagan, the language's developer, sought to combine within a single interpretive processor, the characteristics of two different string and general-purpose macro generators and the provisions to embed multiple infix operator mathematical systems.

Plus is a "Pascal-like" system implementation language from the University of British Columbia (UBC), Canada, based on the SUE[1] system language developed at the University of Toronto, circa 1971.

Altair BASIC was an interpreter for the BASIC programming language that ran on the MITS Altair 8800 and subsequent S-100 bus computers. It was Microsoft's first product (as Micro-Soft), distributed by MITS under a contract. Altair BASIC was the start of the Microsoft BASIC product range.

MAI Basic Four (sometimes written as BasicFour or Basic 4) refers to a variety of Business Basic, the computers that ran it, and the company that sold them (its name given variously as MAI Basic Four Inc., MAI Basic Four Information Systems, and MAI Systems Corporation).

GRASS (GRAphics Symbiosis System) was a programming language created to script 2D vector graphics animations. GRASS was similar to BASIC in syntax, but added numerous instructions for specifying 2D object animation, including scaling, translation, rotation and color changes over time. It quickly became a hit with the artistic community who were experimenting with the new medium of computer graphics, and will remain most famous for its use by Larry Cuba to create the original "attacking the death star will not be easy" animation in Star Wars. A later version that was adapted to support raster graphics was known as ZGrass.

Prolog is a general purpose logic programming language associated with artificial intelligence and computational linguistics.

INTERCAL, a programming language parody, is an esoteric programming language that was created by Don Woods and James M. Lyon, two Princeton University students, in 1972. It satirizes aspects of the various programming languages at the time,[1] as well as the proliferation of proposed language constructs and notations in the 1960s. Consequently, the humor may appear rather dated to modern readers brought up with C or Java.
