EQNCHAR(5)

NAME

eqnchar − special character definitions for eqn and neqn

SYNOPSIS

eqn /usr/pub/eqnchar [ option(s) ] [ −− ] [ file(s) ] │ troff [ option(s) ]

eqn /usr/pub/cateqnchar [ option(s) ] [ −− ] [ file(s) ] │ troff [ option(s) ]

neqn /usr/pub/eqnchar [ option(s) ] [ −− ] [ file(s) ] │ nroff [ option(s) ]

eqn −Taps /usr/pub/apseqnchar [ option(s) ] [ −− ] [ file(s) ] │
troff [ option(s) ]

DESCRIPTION

/usr/pub/eqnchar contains the following troff(1) and nroff(1) character definitions that are not ordinarily available on a phototypesetter or printer. These definitions are primarily intended for use with eqn(1) and neqn(1). eqnchar contains definitions for the following characters:

/usr/pub/apseqnchar is a version of eqnchar tailored for the Autologic APS-5 phototypesetter. If you use apseqnchar, output will not look optimal on other phototypesetters. cateqnchar is more “device-independent,” and should produce output that looks reasonable on any device supported by troff(1). You make link /usr/pub/eqnchar to /usr/pub/cateqnchar or to /usr/pub/apseqnchar. By default, /usr/pub/eqnchar is linked to /usr/pub/apseqnchar.

"The Preprocessor neqn" in the User’s Guide shows the set of character definitions available with eqnchar.
