Thanks PhiLho, Chrisir and quarks, Your help is much appreciated. beginShape does exactly what I want. I appologize for the "double-post." I had made this separate post before I saw Chrisir's last reply to the other post. And I did think it was sufficiently distinct to warrant a separate posting, as PhiLho has commented.

In any case, your indulgence of this newbie is greatly appreciated. Hopefully, as I progress in my understaning of Processing, I can minimize if not eliminate unnecessary postings.
