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]
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

:FORGND SYMMETRY 0-3
VC = RND3 ORA 3
: SAVE FORGND ROTATION
VD = ROTEZ
:FORGND COLOR
COLOR = NXTCOL
