101 Clears Winamp's internal playlist. 
102 Begins play of selected track. 
103 Makes Winamp change to the directory C:\\download 
104 Returns the status of playback. If 'ret' is 1, Winamp is playing. If 'ret' is 3, Winamp is paused. Otherwise, playback is stopped. 
105 If data is 0, returns the position in milliseconds of playback. If data is 1, returns current track length in seconds. Returns -1 if not playing or if an error occurs.

122 Sets the volume to 'data', which can be between 0 (silent) and 255 (maximum).

126 Retrieves info about the current playing track. Returns samplerate (i.e. 44100) if 'data' is set to 0, bitrate if 'data' is set to 1, and number of channels if 'data' is set to 2. (requires Winamp 2.05+) 
127 Retrieves one element of equalizer data, based on what 'data' is set to. 
0-9 The 10 bands of EQ data. Will return 0-63 (+20db - -20db)

11 Enabled. Will return zero if disabled, nonzero if enabled.
