In response to Chris Shenton's question about the availability of REXX for
Unix:  good news, the answer is yes.  The following is an excerpt from the
REXX FAQ:

  This posting contains a list of answers to Frequently Asked Questions
  about the REXX programming language.  The list is maintained by Eric Giguere
  (giguere@csg.uwaterloo.ca) and posted at regular intervals to
  comp.lang.rexx.

  6) Free versions of REXX

      ...(deletion)
      Currently there are two freely-distributable interpreters (with
  source) for Unix machines, both available for anonymous FTP from
  rexx.uwaterloo.ca:


      /pub/freerexx/andersrexx/rexx-0.02a.tar.Z     173500   straight C
            files originally from flipper.pvv.unit.no

      /pub/freerexx/alrexx/rx102.tar.Z              671904   C++ (using GNU G++)
            files originally from tony.cat.syr.edu

  To compile, both interpreters require Lex and Yacc (or suitable clones).
  Both are still beta versions.

  ----------------------------------------------------------------------------
  7) Commercial versions of REXX

     (...companies deleted)

          The Workstation Group       [Various UNIX platforms, also VMS]

The Workstation Group also has a free Unix version for academia.

Anders Christensen has released a new version of "regina", his 
freely-distributable REXX interpreter for Unix.  Version 0.03d can now be
found on rexx.uwaterloo.ca as pub/freerexx/regina/regina-0.03d.tar.Z.  (Note:
this interpreter used to be called "andersrexx".)  Those over in Europe
might find it easier to get it directly from the source at 
flipper.pvv.unit.no under pub/regina/regina-0.03d.tar.Z.  There are some LaTeX
docs included in the source, but only the TeX files.  I've compiled up some
Postscript versions of these and put them in a separate file as
pub/freerexx/regina/regina-docs-ps.tar.Z on my site.

Also:  I've decided to start keeping some OS/2 stuff on my site as well.
For now, I've created an "os2rexx" directory and the only thing in there
so far is the update to OS/2 2.0 REXX that IBM released on 
software.watson.ibm.com.  But if you have anything neat, send it to me and
I'll throw it up...

Some time ago I wrote a REXX program which contained algorithms for evalu-
ating all the common functions.  Its help file says (in part):

  EVX  expression   evaluates any numeric (or, more generally,
  any REXX) expression.  Examples:

  EVX 24*(35/2)-.5        returns 419.5
  EVX max(3.5,3/2,17/3)   returns 5.6666667
  EVX 3*sqrt(2.7)         returns 4.9295030
  EVX reverse(abcxyz)     returns ZYXCBA
  EVX date()              returns 19 Feb 1987  (for instance)

  The expression may contain certain mathematical functions if
  required.  Among the standard REXX functions, the ones using
  numeric arguments and returning a numeric value are:

        ABS(x), MAX(x,y,...,z), MIN(x,y,...,z), SIGN(x).

  Two utility functions are rad(x) and deg(x),  which  convert
  degrees to radians and radians to degrees, respectively.

  Finally,  the  following  algebraic and transcendental func-
  tions are provided:

    sqrt(x)     sin(x)      asin(x)     fctrl(x)
    cbrt(x)     cos(x)      acos(x)     gamma(x)
    ln(x)       tan(x)      atan(x)     lngamma(x)
    exp(x)      cot(x)      acot(x)     erf(x)
    sinh(x)     sec(x)      asec(x)     erfc(x)
    cosh(x)     csc(x)      acsc(x)

This may bring you sufficiently close to your goal of evaluating 2**(.93)
= exp(.93*ln(2)).  While written for CMS REXX, I can't see why it shouldn't
work as well on other platforms.

2.  The Mac version had a bug such that the result of the EDIT command

Dear Paul,

I doubt that there is a public domain version of Logo available.  I'd suggest
that LogoWriter may be the best version for your son to start with.  It might
be possible for you to acquire a copy for home use through a local public
or private school which has a site license for distribution of the probram
to students who are using it as part of their school program.  You would, of
course, have to make contact with the teacher at the school and form some
sort of liaison whereby your son became (informally) part of that teacher's
program.  I wouldn't be surprised if you found a teacher who would be very
pleased to make a home-study copy available in exchange for your passing back
comments on how your son was "taking" to his LogoWriter experiences!  Could
you perhaps work out something along this line with your School of Education?
I know I'd be interested if only I lived in Lafayette!  Good Luck!

A couple of people have asked about the standardization status of Logo.
A few years ago the IEEE standards people hosted a discussion on this
topic that led to further discussions within the Logo community, e.g.,
at an ISTE SigLogo meeting.  It was generally agreed at that time that
it would be very difficult to draft a standard that everyone could
agree to.  There were two main categories of problems:

1.  With respect to the core of the language (the function-calling
mechanism), there is still disagreement between advocates of the
Terrapin dialect and the LCSI dialect.  In the former, there are several
exceptions to the usual argument-evaluation mechanism: IF, EDIT, and
so on.  (That is, to edit procedure foo you say EDIT FOO instead of
EDIT "FOO as the usual mechanism would require.)  In LCSI dialect, the
TO command is the only exception to the usual evaluation rules.

(Briefly, the LCSI version makes it easier to think explicitly about
the Logo language itself, because the rules are more uniform; the
Terrapin version makes it easier to write simple programs *without*
thinking too hard about the language.  It's been argued that Terrapin
style is better for young kids but LCSI style is better for more
advanced learners.)

Another difference, intellectually trivial but important if you want
a standard, is the convention for naming predicates: EQUALP versus EQUAL?.

Recently there has been some motion toward agreement.  Both Terrapin
and LCSI use ? for predicates in their most recent releases (the
original Terrapin convention), but Terrapin seems to be moving toward
the LCSI IF syntax.

2.  Even more important, the parts of the language that actual Logo users
find most important are the ones that are the most machine-specific:
graphics, sound, robotics, and other hardware-dependent extensions to
the core language.  The programming interface (e.g., the editor) also
varies widely among Logo implementations.

Anyway, the upshot is that there is no Logo standard, and so there is
no definitive online document.

----------------------

I am working on a new Logo interpreter.  Its main virtue is that it
provides exactly the same language on PC, Mac, and Unix machines.
Its other main virtue is that it will be distributed free of charge
and with source code.  It's still pretty buggy but I expect to
announce an ALPHA TEST release (that means, I know there are bugs
but you can use it anyway if you want) soon.

You can anonymous ftp to anarres.cs.berkeley.edu and get the file
pub/usermanual which is a brief online reference for this version
of Logo.  It's not "the standard" because there is none, but at
least it's accessible online!

A user has mentioned some confusion about "Edit".
I can't blame him.

The Windows LOGO help is WRONG.
The Text manual is close to right.
There is also a bug in edit when no file is specified (will fix).

For now use

*edit "myprog.lg
 or
*edit "   (for new file) Don't forget to add "to" and "end" lines

For those who don't have windows there is also a version LSRHS logo
for DOS that also works fairly well (execept on hercules monitors).

I know some Logo and I can answer her question but I'm not sure how

The book doesn't have to be second grade reading level, I can

I expect a Whole Book to maybe get that far.

You're probably thinking of LSRHS Logo (developed in my previous
incarnation at the Lincoln-Sudbury Regional High School), which was
sent to comp.sources some years ago.  But it's obsolete; get the file

If you're buying a single copy of LogoWriter, you can save a little
money by buying through a retailer.  I've never seen any version of
Logo on a store's shelves, but some chains (such as Egghead) keep
Logowriter in the warehouse and will sell it at their usual discount.

Also, although all the actual production seems to go on in Canada, the
address given on the box and the order form for supplemental materials
(both of which, alas, I have lost) gives an address in Vermont.  I
imagine this is to avoid Canada's hefty excise taxes.  Perhaps someone
at LCSI could post this.  While they're at it, they might find out
when we can expect a VGA version of Logowriter!
