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 5keyboard is treated as a single- character variable. You cannot use the 5keyboard to input multiple-character variable names like “ab” or multiple-character strings. You must use the alphabet (abc) keyboard when you want to input a multiple-character string. 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 2D keyboard key sets, see “Using the Answer Variable (ans)” on page 2-2-2.

•Note that natural input is available in most applications of the ClassPad. Natural input cannot be used in the geometry measurement box or when entering data into a list.
