Subrange Types

A subrange type represents a part of the base type (any ordinal type). To declare a subrange type, you use the same range syntax as in an array declaration:

type   { enumerated type }   TDay = (Monday, Tuesday, Wednesday,     Thursday, Friday, Saturday, Sunday);   { subrange types }   TWeekend = Saturday..Sunday;   TPercent = 0..100;   TAlphabet = 'a'..'z';
