Chapter 1: Basics 24

Example 2: 2xyE

Tip: When you input a single-character variable, its name appears on the display as an italicized character. This is simply

to let you know that the letter is a single-character variable name.

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 [abc] key set when you want to input a series of characters.

Example: abcE

You can also use the [abc] key set to input single-character variable names. To do so, simply input a single

character, or follow a single character with a mathematical operator.

Example: a*b+cE

Tip: A single-character variable you input using the [abc] key set is identical to a single-character variable you input using

the [Var] key set.

k Using the Alphabet Keyboard

Tap the [abc] tab to the left of the soft keyboard to display the alphabet

keyboard [abc] key set. In addition to the [abc] key set, you can also select

from among three other key sets named [αβγ] (character symbols), [Math]

(mathematics symbols), and [Symbol] (extra symbols).

Use the tabs above the alphabet keyboard (to the right of the keyboard when

using horizontal screen orientation) to select a key set. To return to the [Math1]

key set from the alphabet keyboard, tap the I key in the lower left corner.

k Using the Catalog Keyboard

The “Form” menu of the catalog keyboard lets you select one of the five categories described below.

Func ........ built-in functions (pages 46 and 59)

Cmd ........ built-in commands and operators (page 199)

Sys .......... system variables (page 263)

User ........ user-defined functions (page 196)

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 keyboard.

Tip: Note that user-defined variables and user-defined programs cannot be input using the catalog keyboard. Use

Variable Manager (page 27) instead.
