### Step 1

To get a handler ID, select Data Stream. Select SpiGet Handler for a list of MMPM/2 installed handlers. [Artwork not shown]

Select AUDIOSH$ (audio stream handler) and FSSH (file system stream handler ), and select OK.

Note: AUDIOSH$ and FSSH are the only handlers that can be tested using the PMADDE program. The source code can be modified to create tools that test stream handlers other than AUDIOSH$ and FSSH.

The Active Handlers window then lists the handler names and classes and the IDs for AUDIOSH$ and FSSH. [Artwork not shown]

A handler ID is provided for an active handler to be a source (producer) and a target (consumer). After you have both a producer and consumer stream handler, you can advance to step 2 to create the stream.
