CEEMAC
CEEMAC is a programming language developed in the 1980s for the Apple II family of computers. It was authored by Brooke Boering and published by Vagabondo Enterprises, CEEMAC was designed to be a visual composition language in which the programmer designed dynamic "scores" by programatically controlling color, shape, sound and movement. Additionally, a programmer could then "perform" their score through use of the Apple II keyboard or paddle input devices to introduce additional variation. CEEMAC syntax loosely resembled a combination of BASIC and Pascal and include 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 were included in CEEMAC to aid in score composition. The following is a small CEEMAC sample score: 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.
