MCX BASIC is a dialect of the BASIC programming language. MCX BASIC is designed to follow GW-BASIC, which is one of the standard BASICs running on 16-bit computers. During the creation of MCX BASIC, a major effort was made to make the system as flexible and expandable as possible.

MCX BASIC development environment is very similar to that of the Dartmouth Time Sharing System associated with Dartmouth BASIC. It has a command line-based Integrated Development Environment (IDE) system; all program lines must be numbered, all non-numbered lines are considered to be commands in direct mode (i.e., to be executed immediately). The user interface is almost completely command line.

The original BASIC language was designed on May 1, 1964 by John Kemeny and Thomas Kurtz and implemented by a team of Dartmouth College students under their direction. The acronym BASIC comes from the name of an unpublished paper by Thomas Kurtz. BASIC was designed to allow students to write mainframe computer programs for the Dartmouth Time-Sharing System. It was intended specifically for less technical users who did not have or want the mathematical background previously expected. Being able to use a computer to support teaching and research was quite novel at the time.

The language was based on FORTRAN II, with some influences from ALGOL 60 and with additions to make it suitable for timesharing. Initially, BASIC concentrated on supporting straightforward mathematical work, with matrix arithmetic support from its initial implementation as a batch language, and character string functionality being added by 1965.

The designers of the language decided to make the compiler available free of charge so that the language would become widespread. (In the 1960s, software became a chargeable commodity; until then, it was provided without charge as a service with the very expensive computers, usually available only to lease.) They also made it available to high schools in the Hanover area, and put a considerable amount of effort into promoting the language. In the following years, as other dialects of BASIC appeared, Kemeny and Kurtz's original BASIC dialect became known as Dartmouth BASIC.

Ratings and Reviews

Utterly incomprehensible


MS QuickBASIC had a window for writing programs and a window for showing the results of running the program. This worthless app shows only one window. It apparently shows the results of running the program in the very same window that the program is written in. I could write a program, but it had an error due to so many basic functions being missing, and after that I could not get the program to run again. Incomprehensible. Waste of $5. I saw the recent bad reviews but bought it anyway. My mistake.

Short On Promise

Jon Doh

The author claims this basic is based on GW Basic. However, it is missing so many of the crucial commands in GW Basic so as to render the application useless for serious programming. For example, there is no Locate command, on error goto command nor is there any way to output to a printer. The old simple Sinclair ZX81 computer with membrane keyboard had more functions than are in this app. I truly wish there was a decent basic program for the Mac, but unfortunately there isn’t.

Does not work


I was looking for a simple but usable BASIC. This looked like just what I was looking for. Does not work at all. Can not edit lines of basic by line number. Can not run simple program. Poor to non-existant documentation. Commands listed by HELP do not work. Really disappointed. No other BASIC programming option in App Store. I would think there would be a market for this if it worked. Too bad.

Will check back to see if future releases work as I really want to use this.
