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.

Example

The following is a small CEEMAC sample score:


 SCORE: KT
 :FIRE ORGAN KEY T
 SPEED 
 : - BUT 0
 0
 CLEAR 
 XY1 = $80;$80
 : MAIN LOOP
 F
 :FORGND SYMMETRY 0-3
 VC = RND3 ORA 3
 : SAVE FORGND ROTATION
 VD = ROTEZ
 :FORGND COLOR
 COLOR = NXTCOL
