Although often mistakenly referred to as the Modified Register System, and sometimes as the Record System, the NGSQ numbering system in use today is actually much more comprehensive and flexible.
The NGSQ system, or modified register system, varies from the Register System in that each individual is assigned a number regardless of whether the line is subsequently carried on (whether or not they had children). The individuals who do have descendants are further indicated by the addiion of a plus sign (+) in front of their number.
To look at it visually, here is the layout of a simplified NGSQ report:
