       @mdhughes > So until actual source control in the late '80s/early '90sHistories tend to leave out the earliest history, and this is another example.SCCS counts; it dates to 1973, depending on features.Also, although Larry Wall deserves credit for the feature set of patch(1), diff itself supported patching from its earliest days (1974..1976 or some such):> In diff's early years, common uses included comparing changes in the source of software code and markup for technical documents, verifying program debugging output, comparing filesystem listings and analyzing computer assembly code. The output targeted for ed was motivated to provide compression for a sequence of modifications made to a file.[citation needed] The Source Code Control System (SCCS) and its ability to archive revisions emerged in the late 1970s as a consequence of storing edit scripts from diff.https://en.wikipedia.org/wiki/Diff#Historyhttps://en.wikipedia.org/wiki/Source_Code_Control_System@screwlisp @vindarel @khinsen @kentpitman
