Ah, I misinterpreted the problem in my .tpu-keys, a file tpu-edt users
are commanded to create on first use. The problem was that the line
(define-obsolete-variable-alias 'GOLD-map 'tpu-gold-map "23.1")
had been deleted from tpu-edt.el since 26.3. The file .tpu-keys makes
frequent reference to it. Mine's picked up a lot of tweaks over the
years to make it work on VT100, Sun and Windows keyboards for directly
connected terminals and X-servers. I've therefore given it the guarded
work-around
(if (and (functionp 'version<=) (version<= "28.0.91" emacs-version))
(define-obsolete-variable-alias 'GOLD-map 'tpu-gold-map "23.1"))
I need it to work as far back as Emacs 20.2, which I thinks predates
the function version<=. I'd really like it just to check for GOLD-map
not being defined as a variable, but I couldn't find the syntax for
that.
Richard.
