To specify the draw/non-draw status of a formula ({SEL})
There are two options for the draw/non-draw status of a recursion formula graph.
• Draw the graph for the selected recursion formula only
• Overlay the graphs for both recursion formulas
To specify the draw/non-draw status, use same procedure as that for specifying
generation/non-generation status.
