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.
