-Finally I'm done with the help material. It took me much longer

-the effort. Please pick up the following data sets:
-
-408064: /silo/herbert/redhelp/redref/helptar.Z these are the .tex files
-
-230217 /silo/herbert/redhelp/redref.hlp.Z the windows binary help file
-
-325179 /silo/herbert/redhelp/txt/txttar.Z the bare ascii documents
- thanks to Rainer.
-
-If you want to have a look at the hypertext connections
-as implemented in the windows help file:
-
-- uncompress under unix
-- move the .hlp file to a DOS-Windows (or NT) machine
-- do one of
- (1) double click it with the windows file manager,
- (2) (NT only) enter the command line
- winhelp redref.hlp
- (3) install an icon with title
- REDUCE reference
- and command line
- winhelp
\redref.hlp
- where is the path,
- and then double click the yellow question mark.
-
-Mode (3) allows one to have the book as on line document available
-independent of a reduce session. That is how Microsoft deliver deliver
-their system documentation.
-
-Please have also a look at the index which I have built
-partially automatically, partially by inserting lots of
-\index statements. E.g.
- push the Search button
- and then enter
- polynomial (or any other central item)
- as search item.
-
-================================================================
-
-When working on the material I first had started to keep track
-of any modification, but I gave that up rather soon.
-
-I have modified several formats - latex accepts the object still,
-bit I didn't look at the dvi output. 330 is too much for printing
-anyway.
-
-General remarks regarding the information:
-
-In some places I have modified the REDUCE kernel material substantially.
-I am sure that you will find better words for these points - I am happy
-with *any* improvement. I ran spell on the data sets, but that does not
-find bad grammar or wrong words.
-
-Substantial points are:
-
- SOLVE+its sub-operators and switches
- ARBINT ARBCOMPLEX ROOT_OF ONE_OF EXPAND_CASES
- FULLROOTS FULLPREC
-
- RULE (new type)
-
- LET, WHEN, WHERE
-
- EQUATION
-
- BLOCK
-
- TRUE

-some details:

-
-numeric.tex
-
-I don't like the heading of this chapter, as most of the
-operators described here are more general than just
-numeric. How about "Arithmetic Operators?"
-
----------------------------------------------------------
-REMAINDER:
-
-remainder(sin(2*x),x*y); & SIN(2*X)
-\end{Examples}
-
-\begin{Comments}
-If the first argument to \name{remainder} is not a polynomial, an error
-occurs.
-
-> Here the example and the comment contradict each other
-> sin(2*x) is *not* a polynomial
->>>> not repaired (I have no idea what to write here)
-
---------------------------------------------------------
-
-boolean.tex
-
-
-I have introduced a node which explains the meaning
-of "true". This also could be a member of a "glossary".
-
-The description of NOT
-
-\meta{logical expression} must evaluate to {\it true} or {\it nil}.
-
-is too restrictive. I have deleted this line.
-
-----------------------------------------------------------
-
-command.tex
-
-not very important, but is WS a command? I would prefer
-an operator because its main purpose is to deliver a value.
-
-----------------------------------------------------------
-
-algebra.tex
-
-RESULTANT: please have a look at the TEX-parts: I think that
-the 2nd polynomial should have a different degree (namely m
-as in the INFO parts).
-
-SOLVE: You sell SOLVE below its facilities. According to the
-original description the following examples would fail:
-
-8: solve({x+y=1,x+2y=2,2x+3y=3},{x,y});
-
-{{x=0,y=1}}
-
-9: solve({x+y+z=1,x-y-z=1},{x,y,z});
-
-{{x=1,y= - arbcomplex(4),z=arbcomplex(4)}}
-
-Fortunately they don't! I have commented these restrictions
-in the description.
-
---------------------------------------------------------
-
-switch.tex
-
-RATIONAL:
-
-The \nameref{factorize} command does not accept
-polynomials with rational coefficients.
-
-> this is not true! I have commented this lines.
-
-SOLVESINGULAR:
-
-This switch seems to have no effect at all. At least the
-example doesn't work. Is that a bug in solve or should
-we remove this switch??
