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 zb{Σ} ).

Clear all of user memory (press zb{} ).
