EQNCHAR(6) EQNCHAR(6)
NAME
eqnchar - special character definitions for eqn
SYNOPSIS
eqn /usr/pub/eqnchar [ file ... ] | troff [ option ... ]
neqn /usr/pub/eqnchar [ file ... ] | nroff [ option ... ]
DESCRIPTION
Eqnchar contains nroff and troff(1) character definitions
for constructing characters that are not available on stan-
dard fonts. These definitions are primarily intended for
use with neqn and eqn(1). It contains definitions for the
following characters. WARNING to users of the on-line man-
ual. Unless your terminal has half-spacing, these examples
will be almost unreadable. To get a well printed copy, exe-
cute man -t eqnchar | lp.
ciplus $ciplus$ || $||$ square $square$
citimes $citimes$ langle $langle$ circle $circle$
wig $wig$ rangle $rangle$ blot $blot$
-wig $-wig$ hbar $hbar$ bullet $bullet$
>wig $>wig$ ppd $ppd$ prop $prop$
<wig $<wig$ <-> $<->$ empty $empty$
=wig $=wig$ <=> $<=>$ member $member$
star $star$ |< $|<$ nomem $nomem$
bigstar $bigstar$ |> $|>$ cup $cup$
=dot $=dot$ ang $ang$ cap $cap$
orsign $orsign$ rang $rang$ incl $incl$
andsign $andsign$ 3dot $3dot$ subset $subset$
=del $=del$ thf $thf$ supset $supset$
oppA $oppA$ quarter $quarter$ !subset $!subset$
oppE $oppE$ 3quarter $3quarter$ !supset $!supset$
angstrom $angstrom$ degree $degree$
Different eqnchar definitions may be needed for different
output devices. Alternative files, which are named accord-
ing to the -Tdest option of troff, are listed below.
