virtual void	ReadRecordContents (FormatType omf, ModuleType mod, Linker::Reader &rd)=0
	Reads the record contents, except for the type, length and checksum.

virtual uint16_t	GetRecordSize (FormatType omf, ModuleType mod) const =0
	Calculates the required bytes to write the record, might be less than record_length.

virtual void	WriteRecordContents (FormatType omf, ModuleType mod, ChecksumWriter &wr) const =0
	Writes the record contents, except for the type, length and checksum.

virtual void	WriteRecord (FormatType omf, ModuleType mod, Linker::Writer &wr) const
	Writes the full record.

virtual void	CalculateValues (FormatType omf, ModuleType mod)
	Updates all fields that will be used for writing an OMF module, should be called before output.

virtual void	ResolveReferences (FormatType omf, ModuleType mod)
	Resolves any fields read from an OMF module, should be called after inpnut.

bool	Is32Bit (FormatType *omf) const
	Records are 32-bit if the least significant bit of their record type is set (only meaningful for OMF86Format)

size_t	GetOffsetSize (FormatType *omf) const
	The number of bytes in an offset appearing inside the record, 2 for 16-bit records, 4 for 32-bit records (only meaningful for OMF86Format)
