7. Convenient and Useful Functions
(1) Last entry function
• The EL-9650 is equipped with a temporary memory area that stores expressions
entered for calculation.
• Expressions that have been executed are stored in an executing order until the
temporary memory becomes full. When the capacity of the temporary memory is
exceeded, stored expressions are deleted in order from the oldest. Therefore,
previously entered expressions can be recalled only when they are still stored in the
temporary memory.
• A maximum of 160 bytes can be stored in the temporary memory.
The capacity may vary slightly when there are division codes between expressions.
• Please note that when switching (changing) from the Equation edit mode to One-line
edit mode in the SET UP menu, all numerical equations and graph equations
automatically stored to the temporary memory will be cleared and cannot be
recalled.
Operating instructions:
• To recall the expression evaluated immediately before, press
Ï
. The
previous expression appears on the display.
• To recall the expression evaluated before the previous one, press
Ï
.
Repeat this step to continue recalling expressions in an order from the newest.
• If a recalled expression is evaluated again, it will be added to the temporary memory
as the newest data.
• Data in the temporary memory can be deleted by changing the editor type and
resetting.
