<H4><A ID="SECTION00000020000000000000">
Vertex object:</A>
</H4>
<P>
Unless the first character is |~|, signifying a ``switch'', then the whole
of the braced material is taken as specifying the ;SPMlt;object;SPMgt; for each vertex.
It will be typeset with a circular edge using |[o]...|,
except when there is just a single token ;SPMlt;tok;SPMgt;.
In this case it is dropped as |=0<#127#>|;SPMlt;tok;SPMgt;|<#127#>|, having zero size.
An object can also be dropped at each vertex using the switch |~*<#128#>|...|<#128#>|,
in which case it will be circular, with the current <#129#><I>objectmargin</I><#129#>
applied.
<P>
The next example illustrates three different ways of specifying a |&cir#circ;|
at the vertices.
