.SC "Use on UNIX"
To print a document that contains mathematics on the C UNIX typesetter,
1 eqn files | troff
2 If there are any C TROFF options, they go after the C TROFF part of the command. For example,
1 eqn files | troff -ms
2
A compatible version of C EQN can be used on devices like teletypes and C DASI and C GSI terminals which have half-line forward and reverse capabilities. To print equations on a Model 37 teletype, for example, use
1 neqn files | nroff
2 The language for equations recognized by C NEQN is identical to that of C EQN, although of course the output is more restricted.
To use a C GSI or C DASI terminal as the output device,
1 neqn files | nroff -Tx
2 where .ul x is the terminal type you are using, such as .ul 300 or .ul 300S.
C EQN and C NEQN can be used with the C TBL program[2] for setting tables that contain mathematics. Use C TBL before C [N]EQN , like this:
1 tbl files | eqn | troff tbl files | neqn | nroff
2 .SC "Acknowledgments"
We are deeply indebted to J. F. Ossanna, the author of C TROFF , for his willingness to extend C TROFF to make our task easier, and for his continuous assistance during the development and evolution of C EQN . We are also grateful to A. V. Aho for advice on language design, to S. C. Johnson for assistance with the C YACC compiler-compiler, and to all the C EQN users who have made helpful suggestions and criticisms.
