title: 64-bit-ext
description:
	an openboot draft from 1995 specified a set of words
	for 64-bit arithmetics. These words would be actually
	redefinitions of the doublecell words in 32-bit forth
	systems, but doublecell may be 32-bit on 16-bit forth
	systems. This "proposed standard" uses an "X"-modifier
	in the place of the "D"-modifier for 64-bit-number
	words.

fcode:
	the actual implementation can be looked up in the
	published draft document. Here are the words that
	have been reserved for that usage.

	bxjoin <l@ rx@ rx! wxjoin x, x@ x! /x /x*
	xa+ xa1+ xbflip xbflips xbsplit xlflip xlflips
	xlsplit xwsplit xwflip xwflips xwsplit


comments:
	../../from/Guido.Draheim
	these are just to be used as interface words, a
	simple forth that does not access hardware will
	hardly find a use for them. Otherwise these words
	should be treated as reserved by implementations.
