8.2.2 Ordinal Types

An ordinal type is a range of whole numbers. It includes integer types, character types and subrange types of them.

A character type is represented by the intrinsic type `Char' which can hold elements of the operating system's character set (usually ASCII). Conversion between character types and ordinal types is possible with the intrinsic functions Ord and Chr or type casting techniques.

 
type
  Foo: Char;       { foo can hold a character }
  Num: '0' .. '9'; { Can hold decimal ciphers, is a subrange type of Char }
