- .SC "Use on UNIX"
- .PP
- To print a document that contains mathematics on
- the
- .UC UNIX
- typesetter,
- .P1
- eqn files | troff
- .P2
- If
- there are any
- .UC TROFF
- options, they go after the
- .UC TROFF
- part of the command. For example,
- .P1
- eqn files | troff -ms
- .P2
- To run the same document on the
- .UC GCOS
- typesetter, use
- .P1
- eqn files | troff -g (other options) | gcat
- .P2
- .PP
- A compatible version of
- .UC EQN
- can be used on devices like teletypes and
- .UC DASI
- and
- .UC GSI
- terminals
- which have half-line forward and reverse capabilities.
- To print
- equations on a Model 37 teletype, for example, use
- .P1
- neqn files | nroff
- .P2
- The language for equations recognized by
- .UC NEQN
- is identical to that of
- .UC EQN,
- although of course the output is more restricted.
- .PP
- To use a
- .UC GSI
- or
- .UC DASI
- terminal as the output device,
- .P1
- neqn files | nroff -T\fIx\fP
- .P2
- where
- .ul
- x
- is the terminal type you are using,
- such as
- .ul
- 300
- or
- .ul
- 300S.
- .PP
- .UC EQN
- and
- .UC NEQN
- can be used with the
- .UC TBL
- program[2]
- for setting tables that contain mathematics.
- Use
- .UC TBL
- before
- .UC [N]EQN ,
- like this:
- .P1
- tbl files | eqn | troff
- tbl files | neqn | nroff
- .P2
