HP HP-32S - User Memory and the Stack; Managing Calculator Memory

User Memory and the
Stack
B
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 de
faults, and
Which operations affect stack lift.
Managing Calculator Memory
The HP-32S has 390 bytes of user memory available to you for any
combination of stored data (variables or program lines). SOLVE, /FN,
and statistical calculations also require user memory. (The /FN opera
tion is particularly "expensive* to run.)
All of your stored data is preserved until you explicitly clear it. The
message
MEMORY FULL 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 page 50).
• Clear any or all programs (see page 85).
• Clear the statistics registers (press g|| clear I {2} ).
• Clear all of user memory (press M clear | {ALL} ).
