'''TYPSET''' is an early [[document editor]] that was used with the 1964-released '''RUNOFF''' program, one of the earliest [[text formatting]] programs to see significant use.<ref name="Saltzer.MIT">{{citation

Of two earlier print/formatting programs DITTO and [[TJ-2]], only the latter had, and introduced, [[Typographic alignment|text justification]]; RUNOFF also added [[pagination]].

The name RUNOFF, and similar names led to other formatting program implementations. By 1982, ''Runoff'' (a name not possible before lowercase letters were introduced to filenames) largely became associated with Digital Equipment Corporation and Unix computers. DEC used the terms ''VAX DSR'' and ''DSR'' to refer to ''VAX DIGITAL Standard Runoff''.<ref>{{cite web
