Note:
Executed expressions are stored in a temporary memory in the
executed order. If the temporary memory is full, the oldest data is
automatically deleted. Be aware that
e may not function on
these occasions.
A maximum of 160 bytes can be stored in the temporary memory.
The capacity may vary when there are division codes between
expressions.
When switching from equation edit mode to one-line edit mode in
the SETUP menu, all the numerical and graph equations stored in
the temporary memory are cleared and cannot be recalled.
