Example
global
int my_wav;
int v;
end
process main()
begin
set_mode(640,480,16);
my_wav = load_wav("beat.wav");
write(0,320,30,4,"Use the keyboard to control the music playback.");
write(0,320,50,4,"Key [ENTER] starts the wav.");
write(0,320,60,4,"Key [0] through key [9] changes the song volume.");
write(0,320,180,5,"Volume: ");
write_int(0,320,180,3,&v);
v = 128;
repeat
if(key(_ENTER))
play_wav(my_wav,50);
while(key(_ENTER))
frame;
end
end
if(key(_0)) v = 0; end
if(key(_1)) v = 14; end
if(key(_2)) v = 28; end
if(key(_3)) v = 43; end
if(key(_4)) v = 57; end
if(key(_5)) v = 71; end
if(key(_6)) v = 85; end
if(key(_7)) v = 100; end

if(key(_9)) v = 128; end
set_wav_volume(v);
