My understanding is that this behavior is not any diferrent then makefilename. For example, a makefilename object declared thus:

makefilename foobar%s

when "passed" the message 'symbol dog'

would output symbol foobardog.

Furthermore, unless I'm missing something important, this means that the strcat and makefilename objects provide essentially identical functionality.
I'd like to put in my humble request at this time for a single object which provides for the concatenation of some arbitrary number of symbols AND numbers into a single symbol. If I understood Miller's earlier reply, he's already working on this.

Ben,
