As an untyped language, specific machine addresses are very easy to represent in Forth. This is usually most useful for embedded targets. |

<lang forth> |
|||
$3f8 constant LPT1: |
|||
LPT1: c@ . |
|||
$3f LPT1: c! |
|||
</lang> |

Some architectures may require special fetch and store operators to access ports. For example, [[Open Firmware]] defines l@ and l! for safe 32-bit port writes. |
