Attorney, Agent or FirmInternational ClassG06F 007/06AbstractA single entity contains source lines, being operated on by one or more end users. Within the same entity are entity version and level control data. Individual source lines contain version-related identification variables. After each version or level update by a user, a comparison is made between new and old versions; source line identification variables are modified, and new source lines are added; dependent version information is stored in the entity, and control data is updated. Subsequent retrievals of a version are responsive to the dependent version information, and produce indications of any changes that had been made to dependent versions.Other References
