eqnchar(5)                 DG/UX 4.30                  eqnchar(5)



     NAME
          eqnchar - special equation character definitions for eqn and
          neqn

     SYNOPSIS
          eqn /usr/pub/eqnchar [ files ] | troff [ options ]

          neqn /usr/pub/eqnchar [ files ] | nroff [ options ]

     DESCRIPTION
          Eqnchar contains troff(1) and nroff(1) character definitions
          for constructing characters that are not available on a
          phototypesetter.  These definitions are primarily intended
          for use with eqn(1) 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     ∅
          =wig      ≅     <=>       <=>   member    ∈
          star      *     |<        ≮     nomem     ∉
          bigstar   ∗     |>        ≯     cup       U
          =dot      =     ang       /     cap       (^)
          orsign    \/    rang      L     incl      C
          andsign   /\    3dot      .
                    /\                    subset    (~
          =del      =     thf       ..    supset    ~)
          oppA      ∀     quarter   1/4   !subset   (≅
          oppE      ∃     3quarter  3/4   !supset   ≅)
          angstrom  A     degree    o     scrL      ℓ
          ==<       ≦     ==>       =

     FILES
          /usr/pub/eqnchar

     CAVEATS
          Changes in the underlying font definitions (or other parts
          of the software) will probably disturb the definitions of
          these characters.  However, it is not too hard to adjust
          them yourself.  The characters are built from troff(1)
          characters and local motions;  /usr/pub/eqnchar is a text
          file and can be edited.

          For many of the characters, there is a separate definition
          for neqn(1) and eqn(1).  The neqn(1) definitions are
          approximations at best, since a lineprinter does not have
          the characters or resolution of motion to build characters
          accurately.  They are most useful in previewing material
          that will eventually be typeset.
