2ndclear varsto→ (CLEAR VAR) asks whether to clear all the variables. Choose 1 for Yes. 2ndreset0 (RESET) asks whether to erase memory and settings: choose 2 for Yes. Reset puts every setting back to its start value.

Example 9.6

Clear all variables

1. Store 5 in x, clear the variables with 2nd then sto and 1 for Yes, and read x.
