  pascal OSErr FSMakeFSSpecCompat (short vRefNum,
				   long dirID,
				   ConstStr255Param fileName, FSSpec * spec);
/*	¦ Initialize a FSSpec record.
	The FSMakeFSSpecCompat function fills in the fields of an FSSpec record.
	If the file system can't create the FSSpec, then the compatibility code
	creates a FSSpec that is exactly like an FSSpec except that spec.name
	for a file may not have the same capitalization as the file's catalog
	entry on the disk volume. That is because fileName is parsed to get the
	name instead of getting the name back from the file system. This works
	fine with System 6 where FSMakeSpec isn't available.
	
	vRefNum		input:	Volume specification.
	dirID		input:	Directory ID.
	fileName	input:	Pointer to object name, or nil when dirID specifies
						a directory that's the object.
	spec		output:	A file system specification to be filled in by
						FSMakeFSSpecCompat.
	
	Result Codes
		noErr				0		No error	
		nsvErr				-35		Volume doesnÕt exist	
		fnfErr				-43		File or directory does not exist
									(FSSpec is still valid)

/*	¦ Open a file's data fork.
	The FSpOpenDFCompat function opens the data fork of the file specified
	by spec.
	Differences from FSpOpenDF: If FSpOpenDF isn't available,
	FSpOpenDFCompat uses PHBOpen because System 6 doesn't support PBHOpenDF.
	This means FSpOpenDFCompat could accidentally open a driver if the
	spec->name begins with a period.
	
	spec		input:	An FSSpec record specifying the file whose data
						fork is to be opened.
	permission	input:	A constant indicating the desired file access
						permissions.
	refNum		output:	A reference number of an access path to the file's
						data fork.
	
	Result Codes
		noErr				0		No error	
		nsvErr				-35		No such volume	
		ioErr				-36		I/O error
