CEEMAC

CEEMAC is a programming language developed in the 1980s for the Apple II family of computers. It was developed by Brooke Boering and published by Vagabondo Enterprises, CEEMAC is a visual composition language in which the programmer designs dynamic "scores" by programmatically controlling color, shape, sound and movement. A programmer can then "perform" their score through use of the Apple II keyboard or paddle input devices to introduce additional variation. Syntax loosely resembles a combination of BASIC and Pascal and includes control commands such as GOTO , GOSUB , DO , AGAIN , FOR , SKIP , EXIT and loop control structures such as IF / WHILE and TIL / UNLESS . Additionally, 30 predefined macros aid in score composition. CEEMAC was originally marketed through distribution of a free demonstration program entitled Fire Organ. This program contained several scores created by Boering and other programmers to demonstrate some of the capabilities of the language.
