two objects. This can be done by sliding either or both arrows
sideways a distance given as a TeX dimension enclosed in
<code>@<></code>s: it specifies how far "sideways" the arrow should be
moved, <I>e.g.</I>,
<BLOCKQUOTE><PRE>\xymatrix{
A \ar@<1ex>[dr]^a_{.} \\
& B \ar@<1ex>[ul]^b \ar@<1ex>[r]^c
& C \ar@<1ex>[l]^d_{.} }</PRE></BLOCKQUOTE>

A positive distance will slide the arrow in the "<code>^</code>-direction," <I>e.g.</I>,
the two arrows above are slid in the direction of the labels <I>a</I>,
<I>b</I>, <I>c</I>, and <I>d</I>, respectively; a negative distance in the
"<code>_</code>-direction." The distance <code><@1ex></code> is often appropriate since it
corresponds roughly to the height of letters like "x," in the type size
being used.
