Introduction
You store an object by giving it a name and saving it. An object saved in
this way is called a variable. Any object you create—numbers, equations,
programs, graphics, and so on—can be stored in a variable.
You can create directories and subdirectories to store your variables, or
you can store variables in the default directory (called HOME).
There are four areas within the HP 49G for storing variables: the HOME
directory (and the subdirectories it contains), port 0, port 1, and port 2. By
moving objects you want to keep to port memory, you make more user
memory available for everyday operations.
