Thanks fr your suggestions, Attila. Unfortunately, my code's still not
working -- I don't see a dot and, if I give a non-empty label, I don't
see the label either. Has anyone got anything more to offer?

I had a similar problem and it turned out that the order of commands is
relevant, even at places where it might seem it is not. So I would try
something like:
</pre>
<blockquote type="cite">
<pre wrap="">$map = ms_newMapObj($map_path.$map_file);
$crab_layer = ms_newlayerObj($map);
$crab_layer->set("status", MS_ON);
$dot_class = ms_newClassObj($crab_layer);
$dot_class->set("status", MS_ON);
$image=$map->draw();
$crab_here = ms_newpointobj();
$crab_here->setXY(233, 340, 0);
$crab_here->draw($map, $crab_layer, $image, 0, "");
$image_url=$image->saveWebImage(MS_GIF,1,1,0);
</pre>
</blockquote>
<pre wrap=""><!---->
Note that if you use a point and put text over right over it you might not
see the point (maybe this was intended ?).
Regards,
Attila
