EQNCHAR(7)              COMMAND REFERENCE              EQNCHAR(7)



NAME
     eqnchar - special character definitions for eqn and neqn

     The eqn command is not supported for UTek workstations.

SYNOPSIS
     eqn /usr/pub/eqnchar [ filenames] | troff [ options]
     neqn /usr/pub/eqnchar [ filenames] | troff [ options]

DESCRIPTION
     Eqnchar contains troff and nroff character definitions for
     constructing characters that are not available on a
     phototypesetter.  These definitions are primarily intended
     for use with eqn and neqn.  Eqnchar contains definitions for
     the following characters:

     ciplus    ⊕           ||        ||         square    []
     citimes   ⊗           langle    <          circle    O
     wig       ~           rangle    >          blot      ◼
     -wig      -           hbar      ℏ          bullet    •
     >wig      >           ppd       |          prop      oc
     <wig      ≲           <->       <-->       empty     ∅

     Apseqnchar is a version of eqnchar tailored for the
     Autologic APS-5 phototypesetter.  This will not look optimal
     on other phototypesetters.  Similarly, cateqnchar is the old
     eqnchar tailored for the Wang CAT.  Until a
     phototypesetter-independent version of eqnchar is available,
     eqnchar should be a link to the default version on each
     system.  The standard default is apseqnchar.
