### ByteCard

#### Synopsis

    type
      ByteCard = Cardinal attribute (Size = BitSizeOf (Byte));

#### Description

`ByteCard` is an unsigned integer type which is one "unit" wide. On most platforms one unit has 8 bits, therefore the type is prefixed "byte-" and usually has a range of `0..255`.

`ByteCard` in GNU Pascal is compatible to `unsigned char` in GNU C.

There are lots of other integer types in GPC, see Integer Types.

#### Conforming to

`ByteCard` is a GNU Pascal extension.

#### Example

    program ByteCardDemo;
    var
      a: ByteCard;
    begin
      a := 42;
      WriteLn (a)
    end.
