[1] Of two earlier print/formatting programs DITTO and TJ-2, only the latter had, and introduced, text justification; RUNOFF also added pagination.
By 1982, Runoff (a name not possible before lowercase letters were introduced to filenames) largely became associated with Digital Equipment Corporation and Unix computers.
[3] Morris and McIlroy then moved the BCPL version to Multics when the IBM 7094 on which CTSS ran was being shut down.
[5] This runoff code was the ancestor of roff that was written for the fledgling Unix in assembly language by Ken Thompson.
It actually consisted of a pair of programs, TYPSET (which was basically a document editor), and RUNOFF (the output processor).
