RE: [colorforth] Machineforth IFs

[John Drake <jmdrake_98@xxxxxxxxx>]

One more thing.  It seems that the link I gave you
earlier was misleading.  While the author did a
brave job of explaining colorForth at a time when
it hadn't even been fully released, I now think
his assessment of IF being destructive again in
colorForth is inaccurate.  (i.e. I tested it
myself and it doesn't work that way).  There was
a previous discussion of IF on this mailing list
that can be found at the archives:
