User Memory and the Stack
This appendix covers
The allocation and requirements of user memory,
How to reset the calculator without affecting memory,
How to clear (purge) all of user memory and reset the system defaults,
and
Which operations affect stack lift.
Managing Calculator Memory
The HP 32SII has 384 bytes of user memory available to you for any
combination of stored data (variables, equations, or program lines). SOLVE,
∫
FN, and statistical calculations also require user memory. (The ∫ FN operation
is particularly "expensive" to run.)
All of your stored data is preserved until you explicitly clear it. The message
 & " means that there is currently not enough memory available
for the operation you just attempted. You need to clear some (or all) of user
memory. For instance, you can:
Clear the contents of any or all variables (see "Clearing Variables" its
chapter 3).
Clear any or all equations (see "Editing and Clearing Equations" in
chapter 6).
Clear any or all programs (see "Clearing One or More Programs" in
chapter 12).
Clear the statistics registers (press z b { Σ } ).
Clear all of user memory (press z b {} ).
