u
To input a series of multiple characters
A series of multiple characters (like “list1”) can be used for variable names, program
commands, comment text, etc. Always use the alphabet (abc) keyboard when you want to
input a series of characters.
Example:
0abc
w
You can also use the alphabet (abc) keyboard to input single-character variable names. To do
so, simply input a single character, or follow a single character with a mathematical operator.
Example:
0a
*
b
+
c
w
Tip
• A single-character variable you input using the alphabet (abc) keyboard is identical to a single-
character variable you input using the math (mth) keyboard.

Using the Catalog (cat) Keyboard
The “Form” menu of the catalog keyboard lets you select one of the following five categories:
[Func] (built-in functions on pages 2-4-2 and 2-8-1), [Cmd] (built-in commands and operators
on pages 1-7-4 and 12-6-1), [Sys] (system variables on page
α
-7-1), [User] (user-defined
functions on page 12-5-1), and [All] (all commands, functions, etc.). After selecting a
category, you can choose the item you want from the alphabetized list that appears on the
catalog (cat) keyboard.
Tip
• Note that user-defined variables and user-defined programs cannot be input using the catalog (cat)
keyboard. Use the Variable Manager (page 1-8-1) instead.
• A user-defined function must be stored in the “library” folder to appear in the catalog (cat)
keyboard list when the [User] category is selected.
