1. I/O Rediredtion under DOS and I think UNIX
Can you redirect STDERR messages, ie messages that goto handle 2 in Euphoria eg
puts(2,
"Big Error")
No!!!!!
Why, because this is a fundemental part of DOS design. You don't want to miss an
important error message do you?
You may be able to redirect it, I'm not sure, by changing your settings by using
CTTY. This is _not_ advised!
You can however redirect STDOUT
ie 1. I do it all the time, it helps tracing and is the quickest way to save dat
a.
? the data while > or >> to a file.
So use 1 to output unless it's real important.

The other day I tried to make a small CGI with Euphoria (using OmniHTTP
server for Windows 95). It failed. Why? Because I couldn't make the CGI
return it's output to the browser (or server). Someone told me the trick was
sending the output stream to STDOUT... but didn't work. Does anyone knows
how a CGI sends output?
Euphoria would be great fro CGI programming! From Rob's words: Euphoria is
40-60x faster than Python and/or Perl.

It would. I think (from what I can find so far) that whereas
Un*x STDIN and STDOUT are implemented as streams,
DOS STDIN and STDOUT are devices.
Take a look at WebReflex, a server that is set up to
read and write dos files for it's CGI i/o. It is from
Sapio Designs: http://www.sapio.co.uk/ maybe
some of their help files will answer the question.
Let me know if you get more info. I'd like to use
Euphoria on my own server.

You've got the essence there, you *do* need to send to STDout...
Maybe your cgi just needs a little tweaking.
---- Here's a sample cgi (not in Euphoria though...):
#!/bin/ksh -p
# FingerMe.cgi from my webpage
echo Content-type: text/plain
echo ""
finger crwhite at dcsun1.comp.brad.ac.uk
---- And another one:
#!/bin/ksh
# Beta directory reader
echo Content-type: text/html
echo
echo "<HTML>"
echo "<HEAD><TITLE>File lister test</TITLE></HEAD>"
echo "<BODY>"
echo "<H1>Directory of $1</H1>"
echo "<PRE>"
### snip echo(es of) html stuff
echo "</PRE><HR>"
echo "<BR>"
The point I'm trying to make here is the "Content-type:" and the blank
lines have to be there. Without them the cgi doesn't work.
HTH,
Carl
