Variables and memory management
Introduction
The HP 39gII has approximately 250Kb of user memory,
as well as 80Mb of flash memory.You use the calculator’s
memory to store the following objects:
•
copies of apps with specific configurations
•
new apps that you download
•
home variables
•
app variables
•
user-defined variables
•
variables created through a catalog or editor, for
example a matrix or a text note
•
programs that you create.
A variable is an object that you create in memory to hold
data. The HP39gII has three types of variables: Home
variables, App variables, and User variables.
•
Home variables are available in all apps. For
example, you can store real numbers in variables
A
to
Z
and complex numbers in variables
Z0
to
Z9
.
These can be numbers you have entered, or the
results of calculations. These variables are available
within all apps and within any programs.
•
App variables apply only to a single app. Apps have
specific variables allocated to them which vary from
app to app.
•
User variables are added to the Vars menu via
programs. These variables can be either local to the
program or global. See
Programming
for more
details.
