Hello

please point to the right group if this does not belong here.

using emacs-calc "Embedded Mode", I tried it on my *scratch* buffer,
not working, here is what it does.
I copied this region from the info buffer to do a demo
     The derivative of

                                        ln(ln(x))

     is

ln(ln(x))

when I point to this last line's formula, hit 'M-# e' it then moves
the last line formula to the beginning of the line, then hit 'a d x'
according to the doc to evaluate it, it does not insert the solution
any where and it flashes some horizontal lines in the top line of the
buffer and in the mini-buffer, as if it is not understanding the
typed commands. it is only when I move the pointer to the x it works,
and changes the last line from ln(ln(x)) to 1 / ln(x) x

is this a bug? do I have to point the most inner argument to all nested
operation for it to work?

thanks

So far, so good.

Maybe.
It works fine with the cvs version of emacs, which includes Calc.
What version of emacs are you using?  What version of Calc?
What happens when you start emacs with "emacs -q", and then try what
you did again before doing anything else?

No; you shouldn't have to.

Calc version:2.02f-23
Emacs version: 21.4a-1
$emacs -q works good.

-q hummm... 'do not load an init file'
that is not good, is my .emacs and whatever else being loaded is
causing some confect? so where go from here.

Hi,

how can I download calc? Can it be used on Win (XP)?
I have Emacs 21.3.1 (a mingw build). I installed it simply and I can't see
any calc.el(c) etc.?

Thanks in advance,
P

Thanks!
Unfortunately it seems to me that I would need to build it: it is not part
of "standard" (Windows) Emacs installation :-(
Moreover, it seems that its development is stopped a few years ago :-(
However I may try it...

Do you know any alternative application? The most interesting things in
that for me were: 1) it is part of Emacs (now I see: not exactly); 2)
arbitrary precision; 3) programmability (through elisp?).

Thanks again,
P

It is part of CVS Emacs, and there are prebuilt packages of CVS Emacs
for Windows, for example, at http://www.crasseux.com/emacs

That was before it became part of Emacs.

Thanks for these info!

I checked crasseux; however finally I found EmacsW32 on
http://ourcomments.org/Emacs/EmacsW32.html. It has a conventional Windows
install .exe (http://ourcomments.org/Emacs/DL/EmacsW32/) as well as an
extremly fine description of the whole building process (from "what is
needed exactly and how to download it"...)
(http://ourcomments.org/Emacs/w32-build-emacs.html). (I fell in love with
it for the first sight that is why I advertise it here ;-) It is made by
Lennart Borgman.

You are not the only guy seeing it, so don't get carried off doing
something imprudent.

At least not without the proper virus protection.
