Tip
• As its name suggests, a single-character variable is a variable name that consists of a single
character like “ a ” or “ x ”. Each character you input on the 5 keyboard is treated as a single-
character variable. To input multiple-character variable names like “ab” or multiple-character
strings, you must use the alphabet (abc) keyboard. For more information, see “Using Single-
character Variables” on page 1-6-12.
• For information about the # key that appears in the lower right of all of the math (mth) keyboard
key sets, see “Using the Answer Variable (ans)” on page 2-2-2.
I Using the Alphabet (abc) Keyboard
In addition of the initial alphabet (abc) key set, you can also select from among three
other key sets, within alphabet (abc), named , (character symbols), L (mathematics

S Initial alphabet (abc) keyboard key set

• Note that the initial alphabet (abc) keyboard uses the qwerty key arrangement, which is
similar to a computer keyboard. You can also change to an azerty or qwertz arrangement.
See “16-9 Specifying the Alphabetic Keyboard Arrangement”.
