PROGRAMMING

Storing Mathematical Procedures

With your Programmable Scientific Calculator, complex repeated
calculations are no longer time-consuming chores. All you have to do
is tell the calculator what you want to do in a way it can understand (in
other words, program it).
Your calculator can store one procedure with up to 40 steps. These
"steps" can be either steps (like mathematical functions) or characters
(like numbers). Each function counts as one step. It remembers the
procedure even after you turn off the calculator. You can have more
than one variable in your calculation.
