	Change History (most recent first):

		 <5>	 2/17/92	MH		change extended SampleRate to extended80 SampleRate (2
									instances)
		 <4>	 9/23/91	MH		Swap the comments: Compression Types, and Compression Names so
									that they apply to the appropriate declarations
		 <3>	  8/8/91	JL		Changed Arrays of Byte to Packed Arrays of Bytes - want bytes
									not words. Packed InstrumentChunk Record too.
		 <2>	 7/23/91	JL		Fixed NoneName. Took "p" off of beginning.

	To Do:
