another entry, using the special style <code>@/</code><em>curving</em><code>/</code>. The
simplest styles of <em>curving</em> are the following, shown applied
to an arrow from <I>A</I> to <I>B</I>:
<P><CENTER><BR><IMG WIDTH=258 HEIGHT=118 ALIGN=BOTTOM ALT="displaymath223" SRC="img14.gif"><BR></CENTER><P>
As the last example shows a dimension can be inserted just after <code>^</code>
or <code>_</code> if more or less curving is desired.
<P>
In case it is easier to specify the in- and out-going directions of
the curving then that is also possible: use
<P><CENTER><TABLE BORDER=BASIC CELLPADDING=3 COLS=1><TR><TD> <code>@(</code><em>in</em><code>,</code><em>out</em><code>)</code>
</TABLE></CENTER><P>
<P>
where <em>in</em> and <em>out</em> are one of the following
<em>directions</em>:
<P><CENTER><BR><IMG WIDTH=226 HEIGHT=155 ALIGN=BOTTOM ALT="displaymath241" SRC="img15.gif"><BR></CENTER><P>
<P>
In this case the curving is computed such that the curve begins at the
base entry in the <em>in</em> direction and ends at the target entry
from the <em>out</em> direction (this means that <IMG WIDTH=76 HEIGHT=28 ALIGN=MIDDLE ALT="tex2html_wrap_inline2512" SRC="img16.gif">
and <IMG WIDTH=76 HEIGHT=28 ALIGN=MIDDLE ALT="tex2html_wrap_inline2514" SRC="img17.gif"> are mirror images. See
section <A HREF="node17.html#arrowschanging">2.6</A> for more directions).
