type Char { built-in type }
The built-in type Char holds elements of the operating system's character set (usually ASCII). The Char type is a special case of ordinal type. Conversion between character types and ordinal types is possible with the built-in functions Ord and Chr.
Char is defined in ISO 7185 Pascal and supported by all known Pascal variants.
