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.
