  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.

comment:

 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.
