String Data Type

       

There are two kinds of strings: variable-length and fixed-length strings.

The codes for String characters range from 0�255. The first 128 characters (0�127) of the character set correspond to the letters and symbols on a standard U.S. keyboard. These first 128 characters are the same as those defined by the ASCII character set. The second 128 characters (128�255) represent special characters, such as letters in international alphabets, accents, currency symbols, and fractions. The type-declaration character for String is the dollar sign ($).
