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 33s has 31K bytes of user memory available to you for any combination of
stored data (variables, equations, or program lines). SOLVE,
calculations also require user memory. (The
"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
