It is the style of programming by which bio-code (DNA, CNA, etc) is written for some robot/robotic lifeforms. It is called GOP/GOPs for short.
It is mainly used with mechanoids built out of Living Metal.
Based of Object Oriented Programming, GOP mimics DNA structuring to design a genetic blue print in digital form. Like DNA, a program written in this style can determine, physical features, natural tendencies and even abilities.
