Dartmouth BASIC

Dartmouth BASIC is the original version of the BASIC programming language. The Programming Language Database dates it to 1964 and credits John G. Kemeny and Thomas E. Kurtz, who designed and implemented it at Dartmouth College, which is the origin of its name. It was developed as part of the Dartmouth Time Sharing System and was one of the first programming languages intended to be used interactively, so that students and other beginners could type a program at a terminal and see results at once. The database lists ALGOL 60, BASIC, Microsoft BASIC, True BASIC, HP Time-Shared BASIC, BASIC-PLUS and Altair BASIC among its related languages, showing how widely the dialect family that grew from this version spread across later computers.
