I do not know of any macros for doing this, I have to admit I didn't look that 
hard.  I wrote my own macros for doing this, initially as TeX macros then as 
LaTeX(209|2e) environment(s).

My basic algorithm was to write the exercise and answers out to a file and 
then read them in at the appropriate place in the text.  This is not entirely 
trivial as the writing has to be of the original code; the verbatim stuff from 
the standard TeX/LaTeX(209|2e) came in very handy at this point.

I suppose I should have turned these macros into a separate package and 
submitted it, if there is enough interest I can do this.  Otherwise I could 
let you have a copy of my macros.

Russel.

Subject: Converting LaTex2e to HTML

     Dear TeXhax Digest,
     
     Presumably there's alot of work being done on how to convert LaTex2e 
     to HTML. I want to put lecture notes with equations onto our intranet. 
     Can you point me to where I might find relevant advice.
     
     Latex2html seems a good answer for unix users. However I use DOS, WIN 
     3.11 and OS2 Warp. I did find correspondence on a newsgroup about 
     compiling a DOS version of LaTex2HTML, but there was much discussion 
     about perl and fork, about which I am ignorant. 
     
     Any advice would be gratefully received.
     
     Regards,
     
     David Reynolds

Well, you can either use the macros, Knuth is using in his TeXbook. But it's
(a bit) difficult to implement these. I use some other macros, based on the
package "moreverb.sty", which must be included. 

   ---- solution.sty ----
   %
   % open new file solution.tex for writing
   %
   \newwrite\solutionout
   \immediate\openout\solutionout=solution.tex
   %
   % define environment solutionwrite
   %
   \def\solutionwrite{%
     \@bsphack
     \let\do\@makeother\dospecials
     \catcode`\^^M\active \catcode`\^^I=12
     \def\verbatim@processline{\immediate\write\solutionout{\the\verbatim@line}}%
     \verbatim@start}
   \def\endsolutionwrite{\@esphack}
   %
   % Use this command to close file
   %
   \def\closesolutionfile{\immediate\closeout\solutionout}
   ---- end ----

With these package you will be able to write any string into the file. Here
is an example:

   \documentclass{book}
   \usepackage{moreverb,solution}
   \begin{document}
    \begin{solutionwrite}
      You may use any character in this environment. its although possible to
      write TeX-command into the file:
      \begin{quote}
        Like this quoted block.
      \end{quote}
    \end{solutionwrite}
    %...
    \closesolutionfile
    \input solution.tex
   \end{document}

The only restriction is, that you might not write the string
\end{solutionwrite} into the file. In my opinion there is rather
no need for this. 

Hope, this helps a little bit at least,

  Andi

Subject: Downloading TeX & LaTeX

Hi there,

I'm wondering if you could help. I'm interested in using LaTeX but have 
no idea where & how I can get the programmes. Could you tell me the 
actual file names I need to download from the ctan site please? Oh, do I 
have to have TeX in order to run LaTeX?

Thanks very much for your time.

Subject: Plain TeX query about \csname ... \endcsname

If you do:

  \tracingrestores=1
  {\expandafter\xdef\csname 777\endcsname{555}}
  \bye

you get the message:

  {retaining \777=macro:->555}

in the log file. Page 301 of the TeXbook says that nothing needs to go on the
save stack at the time of a global assignment so I was initially surprised to
get the message. However, page 213 says that \csname ... \endcsname defines the
control sequence to be like \relax if it is not currently defined. So, it would
appear that \csname ... \endcsname first locally defines \777 to be like \relax
and the \xdef then globally redefines it to be 555. If you then do:

  \tracingrestores=1
  {\globaldefs=1 \expandafter\xdef\csname 777\endcsname{555}}
  \bye

it makes no difference. Why? Shouldn't the \csname ... \endcsname globally
define \777 to be like \relax? Or is this some strange exception to the rules?

Thanks in advance for any help.

Colin Mason.

Subject: Memory question

On 29/8/96 I posted a question to TeXhax on a memory problem that I 
was encountering running LaTeX2.09 under Dos on a document with many 
references.  The following reply was sent to me by Jonathan Fine:

> So far as I can tell, the problem is with the lines of code
> >       \def\bibcite#1#2{\global\@namedef{b@#1}{#2}}
> >       \def\@namedef#1{\expandafter\def\csname #1\endcsname}

As I am running \harvardcite as opposed to \bibcite I made the 
following minor adjustment to Jonathan's proposed solution:

  \def\harvardcite#1#2#3#4{\begingroup\expandafter\endgroup
   \expandafter\gdef\csname b@#1\endcsname{#2} 
   \begingroup\expandafter\endgroup
    \expandafter\gdef\csname bhf@#1\endcsname{#2}
    \begingroup\expandafter\endgroup
    \expandafter\gdef\csname bha@#1\endcsname{#3}
    \begingroup\expandafter\endgroup
    \expandafter\gdef\csname bhy@#1\endcsname{#4}}

This appears to have fixed my problem.  I hope that others might
find this correspondance useful.

Regards,

Mark Freeman.
