1.3.6 The FIB
The main stream of the Word Binary File Format begins with a File Information Block, or FIB. The FIB specifies the locations of all other data in the file. The locations are specified by a pair of integers, the first of which specifies the location and the second of which specifies the size. These integers appear in substructures of the FIB such as the FibRgFcLcb97. The location names are prefixed with fc; the size names are prefixed with lcb.
