A string type declared without a maximum size is given the size 255.
String constants are written in quotes; for example: 'Turbo', 'That''s all'. Notice how two consecutive single quotes are used to indicate a single quote in a string.
These operators can be used with string type values: +, =, <>, <, >, <=, >=.
