Elementary Data Types - Strings
 
There are two kinds of strings:
 
  - Variable-length string
      A variable-length string is a sequence of up to 32,767 characters.
      The codes for these characters range from 0-127 for regular ASCII
      (American Standard Code for Information Interchange) characters, and
      from 128-255 for the extended-ASCII characters. See the on-line
      <ASCII CHARACTER CODES TABLE> for examples of each type.
 
  - Fixed-length string
      A fixed-length string contains a declared number of characters,
      no more than 32,767.
      Like variable-length strings, a fixed-length string contains
      characters with codes ranging from 0-255.
