Thanks, Wally. The new user guide is very tasty indeed, a friendly
and informative addition to the package.
Coincidentally, I've put some finishing touches on my Xy4 helper
programs (U2 frames and documentation encoded below). The most
visible change is that encoded SEarch wildcards are now formatted
with the same color (MoDe 79) as actual wildcards, so that the real
and faux entities look exactly alike, as the attached screen shot
shows.
I couldn't resist dubbing the formatted views produced by XYFMT and
XYTOG as "overcooked" encodings, a nod to the fact that they can't be
decoded directly, at the DOS prompt, with XYDEC.COM, but first have
to be stripped of the stuff that would mess up decoding (something
the helper frames do hands off, but that can also be done manually
with XYFMT2).
Bon appetit!
