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,[1]
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.[2]
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.[2]
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.[1]
Example
The following is a small CEEMAC sample score:[3]
SCORE: KT :FIRE ORGAN KEY T SPEED [0,0] : - BUT 0 0 CLEAR [0,0] XY1 = $80;$80 : MAIN LOOP F :FORGND SYMMETRY 0-3 VC = RND3 ORA 3 : SAVE FORGND ROTATION VD = ROTEZ :FORGND COLOR COLOR = NXTCOL
