2.5 Strings

Strings are used in write statements, in other output statements (such as error messages), and to name files. A string consists of any number of characters enclosed in double quotes. For example:

     "A String"

Lower case characters within a string are not converted to upper case.

The string "" represents the empty string. A double quote may be included in a string by preceding it by another double quote. Thus "a""b" is the string a"b, and """" is the string consisting of the single character ".
