Storing Data into Variables
The HP 32II has 384 bytes of
user memory
: memory that you can use to store
numbers, equations, and program lines. Numbers are stored in locations
called
variables
, each named with a letter from
A
through
Z
. (You can choose
the letter to remind you of what is stored there, such as
B
for
bank balance
and
C
for the speed of light.)
