/*	class O80Data
	-------------

	Subclass of "TapeData".

	A "O80Data" instance contains data from a .p, .o or similar file or converted to this format.
	A "O80Data" instance contains one data block.

	As all TapeData classes O80Data defines or implements conversion creators for CswBuffer:
	- new O80Data(CswBuffer const&) and
	- new CswBuffer(O80Data const&, uint32 ccps).

	And static file i/o methods:
	readFile (cstr fpath, TapeFile&) and writeFile (cstr fpath, TapeFile&)
