The Memory Playlist Sample (CLOCK) illustrates the use of the memory playlist feature of OS/2 multimedia. The memory playlist feature provides for easy manipulation of multimedia data in memory to create unique effects based on user input or other dynamic events. In the case of the Memory Playlist Sample, multimedia data is manipulated dynamically to create sound effects (chimes) based on the time. The sample program also illustrates the use of the captioning flag provided by OS/2 multimedia. The Memory Playlist Sample uses this flag to decide if it should provide users with a visual cue of chimes.
