Hi, I really appreciate your response.  What I'd like to know is, how do I
look up this information on my own?  I use this mailing list generally as a
last resort when I can't find the answer myself.  In the case, I did a lot
of research before I asked my question, but couldn't get a definitive
answer.  If you could point me to the documentation that you are using I'd
greatly appreciate it.

Thanks,

Larry Cohen
