Help for tpu-edt Legacy Users

[Richard Wordingham]

For a legacy user who has been happily using the TPU-EDT key bindings,
buffers and replacement commands for decades, where should I put the
now removed tpu-edt and tpu-extras packages?  (There are three files -
tpu-mapper.el is not to be forgotten.)  Should they just go in
directory site-lisp, or maybe lisp/obsolete?  I've currently put
the versions from Emacs 26.3 in ~/.emacs.d/obsolete, and tpu-edt.el (the
only one I've been using) is so far working fine in Emacs 28.0.91.  I'm
currently explicitly loading (function load) them, as I had been for
previous versions of Emacs.

Richard.

These files were not removed yet, they are in lisp/obsolete.

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.

Is 'boundp' what you want here?

Yes, that seems to do the trick.  (I can't test Emacs 20.2 until
tomorrow.)  Thank you.

Richard.
