Hi Gabor,
Thanks very much for your reply. I was hoping to ask a follow-up question. Can
you explain why it's better to use transform than to use within? The main
difference between the two functions seems to be that within allows one to use
variables created in a step (e.g., A and B) to create other variables within
the same step (e.g., C = A + B).
Thanks again.
Paul
