CEEMAC

Designed by: Brooke Boering

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:

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 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.
