To anyone familiar with the apple2 version of logoWriter:

	Is there a simple way to reconfigure the printer setup to be in
onather slot besides slot 1? All the choices for different interface cards
all seem to assume slot 1.  The docs seem to make no mention of changing 
printer slots, just diskdrive slots...


Thanks for any help.

   ....  Also, the Lego-Logo people publish
   plans for a build-it-yourself turtle out of Lego. 

As a warning, the Lego turtle is a bit disapointing once you've gotten
used to screen turtles or higher-tech robot turtles.  I've been using
it (not with Logo, with Scheme, but that is irrelevant) and it is
frustrating trying to calibrate how many seconds of turning for angles
of various measures, or even getting the forward/backward motion
reliable.  The design is completely open-loop -- there is no
"odometry" to measure how far the wheels actually turn, so you just
have to go by the times.  Closed curves rarely close, etc.  Another
limitation is that there is no pen up/down effector, so the pen is
always down (or always up -- you choose).

On the plus side, the Lego stuff is "open" -- you can build
whatever you want out of it, not just a turtle.  Or you can change the
design of the turtle -- e.g. you could try adding odometry or pen
control (if you succeed at either of these I'd love to hear from you).

   I don't have addresses handy but I'll try to look it up.

The interface is similar to the one used by Lego-logo.  The Bots interface has
4 motor ports and 4 sensor ports.  (BTW, we got all 4 sensor ports to work with
the lego optical sensor)  In addition to the sensor state and state cycle count
provided by the Lego-Logo interface, the Bots interface also provides the cycle
"rate," and allows for callibration of optical sensor sensitivity.

The interface can control other things as well, such as Capsella.

Bots produces HyperCard based software for use with the interface on the Mac.
The documentation describes the interface's command protocol (although there
are a few mistakes) well enough so that the interface can be controlled from
any programming language capable of serial I/O.  As I understand it, there a
a few versions of Scheme which support this interface.

I am working on software to control the interface from the M2Amiga Modula-2
language on the Amiga.  I may also provide software for PCQ, a public domain

Our son is almost four years old and can type a few DOS commands and use

non-Windows would be ok, to.  Does anyone know where I can find one that

Atart used to ship a Logo interpreter free of charge in
the ST boxes, but for some reason had discontinued this 
practice. The publishing company iwt has a Logo called
"iwt Logo for Atari" which represents a major effort
in computer archeology. The program author found 4 different

and managed to write a Logo to cope with all of them. 
We are currently testing this Logo (we are preparing a
report on the Logo interpreters available for German schools
for "Log In", a German magazine about computers in the schools),
but the tests have not been completed. This information in
on the basis of what is noted in the handbook.

You don't specify what level of abstraction the WIMP features are
specified at, low level wiget type facilities, or high level packaged
utilityies, but...

Last summer I did some work at Sussex with the Poplog Prolog system
interfacing it to the Athena X system.  There was already an interface
for the Pop11 language so what I did was to hook the Prolog into the
Pop11.  The net result was a set of new "builtin" predictes in Prolog
which behaved like write/1 etc.  (Admitedly much of this took advantage
of the Pop11 datastructures to store wiget info thus avoiding explicit
asserts and retracts at the Prolog end).

Yes, these are, strictly, side effect predicates, but I don't see
anyway around that.  If your Prolog has a good C interface the same
technique should work, hook Prolog predictes into foreign language
functions that perform the necessary graphics.

What's a good way to represent sets of (possibly non-ground) terms in a setting
where terms are regarded as identical if they are variants of one another?  (Two
terms are variants of one another if each is an instance of the other, i.e. if
one is obtained from the other by "systematically" renaming variable.)  For
ground terms, a convenient and efficient way to represent sets is as sorted
lists without duplicates.  Doing something like this for non-ground terms may
involve comparing variables.

If variable-name correspondence between terms in the set is not important, a
solution is to independently numbervars each term, thereby reducing each to a
canonical ground form.  This would be the case, for example, for a set of
clauses.

But if variable-name correspondence between terms in the set _is_ important, as
for example if it's a set of atoms within a clause, this device will not work.
For example, the equivalence of the sets
		{p(X, a), p(Y, b)} and
		{p(U, b), p(V, a)}
does not seem to be easily detectable.

Have been using Quintus prolog for about a year and a half now. It is 
mostly ok. Has a wide range of library predicates including one for object
oriented programming - ProTalk. There is an X-window interface which maps
the C code for X-Lib and X-Toolkit more or less directly onto prolog calls.
It took some time to figure out how to use the graphical tools but this was
more a consequence of the nature of X-Lib and the X-toolkit themselves
rather than the  prolog side. I have never programmed X-windows in C but I 
guess doing it in prolog is far easier once you have grasped the philosiphy.
Apart from Quintus prolog I have only ever used an interpreter written in
pascal so I cant comment on how it rates with other compilers in terms of 
efficency. I have had some problems however with strange bugs in the
compiler - every now and then we get segmentation faults with entirely legal
code. These did not happen with version 2.5 but version 3.0 was pretty bad.
Version 3.1.1 is much  better but they still occur. The only way to stop them
is to try alternatives to the already valid code until they go away.
All in all it provides quite a nice environment to work in.

Hi, I am currently teaching myself PROLOG as I will be doing next

During this semester break I have borrowed several books on the subject

The following *IS NOT* an assignment or tutorial excercise issued by

still important my question is:  

Can anyone please solve this simple logic problem and e-mail to me the
solution, including if possible some comments.

I am not exactly sure what you are trying to do or the problem you are 
having but I found the following book ESSENTIAL for using PROXL/PROXT:

   Young, Douglas A. 1990

   The X Window System Programming and Applications with Xt:
   OSF/Motif Edition.

   (Prentice Hall, Inc.)

This book is only concerned with the C Language interface to the OSF/Motif
toolkit but since the Quintus manuals only describe the interface between
Prolog and C and not the the details of the toolkit itself, it is pretty
indispensible.

This is a pure Prolog solution, to make it a little bit
more interesting. The method is useful for other puzzles on
small finite domains (as usually given by humans to humans).
I am wondering if someone tried to compile formulas with
negation or constraints to something that looks like "solve/1".
I hope it is also fine food for hungry partial evaluators.
As is, it takes exactly the same time in emulated Sicstus 2.1
and in BinProlog (140ms on a Sparc IPC). I would be curious to know 
how much it takes on faster Prologs and how fast it can be
made by partial evaluation. Do constraint logic programming
languages perform significantly better on this kind of problem
than a partially evaluated Prolog solution?
