String Data Type

Description

There are two kinds of strings:

• Variable-length strings, which can contain up to approximately 2 billion (2^31) characters (approximately 64K (2^16) characters for Microsoft Windows version 3.1 and earlier).
• Fixed-length strings, which contain a declared number of characters (less than 64K).

The type-declaration character for String is $ (character code 36). The codes for String characters range from 0 to 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.
