audio files and delays

[Peter Quain]

there's probably some much simpler way to do this that i don't know 
about, but you could do it with code.

Need to


Dim mySoundBuffers As SoundBufferCollection
Set mySoundBuffers = new SoundBufferCollection
mySoundBuffers.Add sBuffer1, , ,
mySoundBuffers.Add sBuffer2, , ,
mySoundBuffers.Add sBuffer3, , ,


'Spin through the collection and debug.print the name

Dim r As RteObject

Dim nIndex As Long

For nIndex = 1 To newCollection.Count

Set r = newCollection.Item(nIndex)

If Not r Is Nothing Then

  Display.Canvas.Text 5, nIndex * 20, "Collection object " &_

"# " & nIndex & ": " & r.Name

End If

Next 'nIndex
