Details

The LIFO stack is 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 The Annotate Data Set for a description of the LIFO stack.
