Thanks Bob,
Yes, I'm remembering too, that by commenting out the NAME element in the
CLASS section the symbols will display on the map, but not the legend.
I guess it wasn't just my imagination again :-)

Bob,
I do this type of thing with a dummy LEGEND block in the Mapfile.
Map:

Here's one that I thought I remembered seeing somewhere, but can't
figure it out. I want to be able to hide certain classes from
displaying in the legend.
I have a layer that depicts public facilities. I use different colors
to show if each facility has a certain service, or does not. This
results in a lot of redundant symbols, just of different colors. I'd
like to show the symbols just once per symbol type, and explain the
colors at the bottom. Can this be done, or am I imagining things
(again)?
