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 — and .

%CHG %TOTL MU%C MU%P

COST PRICE M%C

COST PRICE M%P

Shared variables

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?
