Also, you can always copy special characters by using the CHARS menu
(

…±) if you don’t want to memorize the keystroke combination that

produces it. A listing of commonly used

~‚keystroke combinations

was listed in an earlier section.

algebraic expressions see Chapter 2 of the calculator’s User’s Manual.

Organizing data in the calculator

You can organize data in your calculator by storing variables in a directory
tree. The basis of the calculator’s directory tree is the HOME directory
described next.

The HOME directory

To get to the HOME directory, press the UPDIR function (

„§) -- repeat as

needed -- until the

{HOME} spec is shown in the second line of the display

header. Alternatively, use

(hold)

§

. For this example, the HOME

directory contains nothing but the CASDIR. Pressing

J

will show the

variables in the soft menu keys:

Subdirectories

To store your data in a well organized directory tree you may want to create
subdirectories under the HOME directory, and more subdirectories within
subdirectories, in a hierarchy of directories similar to folders in modern
computers. The subdirectories will be given names that may reflect the
contents of each subdirectory, or any arbitrary name that you can think off.
For details on manipulation of directories see Chapter 2 in the calculator’s
User’s Guide.
