Sharing Variables Between Menus
If you compare the MU%C menu and the MU%P menus, you’ll see that
they have two menu labels in common ––

MU%C MU%P
The calculator keeps track of the values you key in according to those
labels. For example, if you key in COST and PRICE in the MU%C menu,
exit to the BUS menu, and then display the MU%P menu, the calculator
retains those values. In other words, the variables are
shared
between
the two menus.
Example: Using Shared Variables. A food cooperative buys cases of
canned soup with an invoice cost of $9.60 per case. If the co-op
routinely uses a 15% markup on cost, for what price should it sell a case
of soup?
