I set

Syntax: set of type

The base type of a set must be an ordinal type with no more than 256 possible values.

The ordinal values of the upper and lower bounds of the base type must be within the range 0..255.

A set constructor, which denotes a set type value, is formed by writing expressions within brackets. Each expression denotes a value of the set.

The notation [ ] denotes the empty set, which is compatible with all set types.

Example:

Type
   Day = (Sun, Mon, Tue, Wed, Thu, Fri, Sat);
   CharSet = set of Char;
   Digits = set of 0..9;
   Days = set of Day;{ Set constructors }
   ['0'..'9', 'A'..'Z', 'a'..'z', '_']
   [1, 5, I + 1 .. J - 1]
   [Mon..Fri]
