Macintosh BASIC, or MacBASIC, was both a comprehensive programming language and a fully interactive development environment designed by Apple Computer for the original Macintosh computer. It was developed by original Macintosh team member Donn Denman,[1][2] with help from fellow Apple programmers Marianne Hsiung, Larry Kenyon, and Bryan Stearns,[3] as part of the original Macintosh development effort starting in late 1981.[4][5] Andy Hertzfeld said, "A BASIC interpreter would be important, to allow users to write their own programs. We decided we should write it ourselves, instead of relying on a third party, because it was important for the BASIC programs to be able to take advantage of the Macintosh UI, and we didn't trust a third party to 'get it' enough to do it right."[6]
MacBASIC was released as beta software in 1985, and was adopted for use in places such as the Dartmouth College computer science department, for use in an introductory programming course.[citation needed] In November 1985, Apple abruptly ended the project as part of a deal with Microsoft to extend the license for BASIC on the Apple II.[7][8] Although Apple retracted MacBASIC, unlicensed copies of the software and manual still circulated, but because MacBASIC was no longer supported by Apple and was not designed to be 32-bit clean, interest eventually died out.[citation needed]
Benchmarks published in the April 1984 issue of BYTE magazine suggested that MacBASIC had better performance as compared to Microsoft's MS BASIC for Macintosh.[9][dubious ] The language included modern looping control structures, user-defined functions, graphics, and access to the Macintosh Toolbox. The development environment supported multiple programs running simultaneously with symbolic debugging including breakpoints and single-step execution.[2]
