E. Saltzer, which ran on MIT's CTSS operating system in the mid-sixties. This name came from the common phrase of the time "I'll run off a document." Bob Morris ported it to the 635 architecture and called the program `roff' (an abbreviation of `runoff'). It was rewritten as `rf' for the PDP-7 (before having UNIX), and at the same time (1969), Doug McIllroy rewrote an extended and simplified version of `roff' in the BCPL programming language. The first version of UNIX was developed on a PDP-7 which was sitting around Bell Labs. In 1971 the developers wanted to get a PDP-11 for further work on the operating system. In order to justify the cost for this system, they proposed that they would implement a document formatting system for the AT&T patents division. This first formatting program was a reimplementation of McIllroy's `roff', written by J. F. Ossanna. When they needed a more flexible language, a new version of roff called nroff (Newer roff) was written. It had a much more complicated syntax, but provided the basis for all future versions. When they got a Graphic Systems CAT Phototypesetter, Ossanna wrote a version of nroff which would drive it. It was dubbed troff for typesetter roff, although many people have speculated that it actually means Times roff because of the use of the Times font family in troff by default. As such, the name troff is pronounced `t-roff' rather than `trough'." Related languages
