sccs Abbrev. for source code control system. A utility program, developed initially to run under UNIX, that keeps track of a set of versions and variants of a text file (usually source language). Sccs can retrieve any one of the set of versions and variants it holds, and can receive new versions or variants together with a commentary concerning who made the change and what has changed from the previous version or variant. An important feature of sccs is that it does not keep the full source text of each version or variant. Instead it keeps one full text and a set of differences between that version and all the other versions and variants. Hence sccs provides a more economical means of storing a module with many versions and variants than, for example, storing them all in separate files.
