Definition: The String data type is used for text data when the appearance of text does not bear meaning. This is true for formalized text, symbols and formal expressions, and all kinds of names intended for machine processing (e.g., sorting, querying, indexing, etc.).
String data is left justified (i.e., no leading blank space) with trailing blanks optional. Any displayable (printable) ACSII characters (hexadecimal values between 20 and 7E, inclusive, or ASCII decimal values between 32 and 126), except the defined escape characters and defined delimiter characters.
