Loading Program Library Programs
This calculator comes with a built-in Program Library that provides you with a collection of
application programs. Unlike programs you input yourself, you must use the procedure
described below to load Program Library programs into memory before you can run them.
•The Program Library is divided into sub-libraries.
•You cannot edit or reference the contents of a Program Library program.
To load the program “FACT” (JAPAN sub-library)
1. On the icon menu, select W.
2. Use the function keys to execute the LOAD command.
6(g)5(LOAD)
3. Use the fand ccursor keys and wto select first the
sub-library and then the program.
(cc...) “JAPAN” w
(cc...) “FACT” w
(The message “Load Complete!” appears for about one
second. After that, the display returns to normal.)
•You can also jump to a specific location in the sub-library by inputting a letter.
Inputting the letter “F” (aF), for example, causes the highlighting to jump
to the first program name in the sub-library that starts with “F”.
•The message “Memory Full!” appears for about one second when there is not
enough memory to store the program. Delete data you no longer need and try again.

2
•The screen shown to the right appears when a
program with the same name as the one you are
trying to load already exists in memory. Perform one
of the following key operations when this happens.
“YES” 1....... Replaces the existing program with the one you are loading.
“NO” 6....... Skips the program with the same name and continues with the load
operation.
“AC” A....... Aborts the load operation.
4. Press Ato return to the Program List screen.
Now you can run the program using the same procedures that you use to run your own
programs.
Important!
•Executing some programs change the setting of your calculator. Be sure to check
your calculator settings before executing a new program.
•Access the Web site at the following URL for detailed descriptions of each program
does and how to use them:
