Looks like its going to be a long night for me!
Anyways, one more question, and then I will let you go...I promise.

why do we need to use 'triangulate' procedure to draw a polar_contour
plot? please excuse my ignorance regarding this. because right now it
seems like this is the last bone of contention. Triangulate is
standing between me and the solution.

BTW...have u noticed the uncanny resemblance between 'strangulation'
and 'triangulation'....??

he he he ....
