AbstractCodes can be viewed as mechanisms that enable relations of signs and their components, i.e., semiosis is actualized. The combinations of these relations produce new relations as new codes are building over other codes. Structures appear in the mechanisms of codes. Hence, codes can be described as transformations of structures from some material systems into others. Structures belong to different carriers, but exist in codes in their “pure” form. Building of codes over other codes fosters their regulation. There are several ways to add codes: by types of transformation of structures involved in codes; by dimensions of pragmatics, semantics, and syntactics; through “abstract universals versus precise forms” relations; and by regulation levels in the “organism – environment” relations. More complicated codes are formed based on the interrelations of codes built over. These interrelations are presented as a conceptual chart, which reflects the way typical semiotic formations emerge in mind based on the interrelations of various codes. It also presents the related sociocultural semiotic systemities: motives, needs, aspirations, moral values, purposes, language-like systemities, fundamental frames, patterns of culture, etc.
