Paradigm Visual composition language
Designed by Brooke Boering
Developer Vagabondo Enterprises
Platform Apple II

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,[1]

CEEMAC was designed to be a visual composition language in which the programmer designed dynamic "scores" by programmatically 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.[2]

CEEMAC syntax loosely resembled a combination of BASIC and Pascal and include control commands such as [GOTO](/wiki/GOTO "GOTO"), [GOSUB](/wiki/GOSUB "GOSUB"), DO, AGAIN, FOR, SKIP, EXIT and loop control structures such as [IF](/wiki/Conditional%5F%28programming%29 "Conditional (programming)")/[WHILE](/wiki/While%5Floop "While loop") and TIL/UNLESS. Additionally, 30 predefined macros were included in CEEMAC to aid in score composition.[2]

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 = <span class="katex"><span class="katex-mathml"><math xmlns="http://www.w3.org/1998/Math/MathML"><semantics><mrow><mn>80</mn><mo separator="true">;</mo></mrow><annotation encoding="application/x-tex">80;</annotation></semantics></math></span><span class="katex-html" aria-hidden="true"><span class="base"><span class="strut" style="height:0.8389em;vertical-align:-0.1944em;"></span><span class="mord">80</span><span class="mpunct">;</span></span></span></span>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.[1]
