## 9.303 Word

### Synopsis

    type
      Word = Cardinal;

or

    type
      Word (n) = Cardinal (n);

### Description

``Word'` is the "natural" unsigned integer type in GNU Pascal. On most platforms it is 32 bits wide and thus has a range of ``0..4294967295'`. It is the same as section 9.37 Cardinal, introduced for compatibility with other Pascal compilers.

As an extension, GPC allows to use ``Word'` as a pseudo-schema to produce types with a specified size in bits; for example

    type
      Word16 = Cardinal (16);

defines an unsigned integer type with 16 bits. The same mechanism works for ``Cardinal'` and ``Integer'`, too.

``Word'` in GNU Pascal is compatible to ``unsigned int'` in GNU C.

There are lots of other integer types in GPC, see section 8.2.3 Integer Types.

### Conforming to

ISO Pascal does not define ``Cardinal'`. (However see section 8.2.10.1 Subrange Types.)

The ``Word'` type appears in Borland Pascal and Delphi, too, where it is a 16-bit unsigned integer type.

### Example

    program WordDemo;
    var
      a: Word;
    begin
      a := 42;
      WriteLn (a)
    end.
