W@ "w-fetch"

( addr -- x )

Fetch, zero-extend and return the 16-bit word at addr.
The system may require addr to be aligned on a 16-bit word boundary.


This word is present in Open Firmware and may be found in many other Forths.

For sign-extending words fetch, one may use the word SW@ or the word <W@
used in Open Firmware.
