Comparisons
The last-in, first-out (LIFO) stack provides a way
to save previously calculated coordinates. It enables you to retain
coordinate values for later use by utility functions without recalculating
those values. In order to save coordinate values in the stack, you
must explicitly push them onto the stack. See
Using the LIFO Stack for a description of the LIFO stack.
