oh .. and this DOES generate an error does it ? .. perhaps you should

I don't think it does. What makes you think it does? (Where's your code?)

That depends.

Maybe there's someone in your team of "expert perl programmers who have
profound knowledge" that knows the difference between read and sysread?

The '>' means open for output, so omit it.
Use one of these to get what you want:
open(LIST,'c:/blah') || die "..";
open LIST,'c:/blah' or die "..";
What you have is the same as
open LIST, ('c:/blah' || die "..");
('or' and '||' have different precedence. Weird, but true.)

There's a tutorial at:
http://www.5sigma.com/perl/schwtr.html
Put this at the top of your program:
sub show {
local $" = ',';
local $, = ",\n";
local $\ = "\n";
print map {ref $_? "[@$_]": $_} @_;
}
Now try:
my @stuff = <LIST>;
show ['just','a'],'test';
show @stuff;
show map { [$_, (split /,/)[0]] } @stuff;
show
sort { $a->[1] cmp $b->[1] }
map { [$_, (split /,/)[0]] }
@stuff;
show
map { $_->[0] }
sort { $a->[1] cmp $b->[1] }
map { [$_, (split /,/)[0]] }
@stuff;
Of course, there's another way to sort:
my @stuff = <LIST>;
my %places = ();
foreach (@stuff) {
$places{$_} = (split /,/)[0];
}
print sort { $places{$a} cmp $places{$b} } @stuff;

There's a 'rename' command.. check the manual. If you need a tutorial I
recommend "Learning Perl" from O'Reilly.

Great, you're repeating me again. Please wrote what I wrote before

Stop right there. You're completely out of line. I *explicitly*
directed people to read *exactly* what Larry had said about this and
to infer their own conclusions. I purposefully presented absolutely no
interpretation whatsoever. I did not paraphrase. I did not spread rumor.
I did not employ hearsay. I did not use special knowledge granted me
in private audience. I used direct quotes only, without commentary,
and included links to the exact documents so you could read the whole
thing in context, as well as the rest of thread. I told *you* to
read it and to draw *your own* inferences about what his words meant.
I again encourage you to please do so.
And please stop accusing me of doing something I went so extremely far
out of my way to avoid doing or even of giving the impression of doing.
Thank you.

Your question is not clear as to what you mean
by saying "append to beginning of file".
If in case you are worried about the HTTP
headers you need to emit before you
start with the HTML body then you have
to use CGI.pm module to make life easy.
You can create headers easily ..
use CGI;
my $page= new CGI ;
print $page-> header () ;
print $page->start_html();
//enter code for rest of dynamic page here...
print $page->end_html();
exit;

Well, it works, but it doesn't do what you think it does.
Go read on the <> operator, and see what's it doing in list context.
Then you should be able to design your algorithm better.

Is memory usage the only good reason for not 'putting files into arrays' to much?

If you are using CGI.pm then these scripts
will automatically know whether they have
been invoked by a web server or from the
command line.
If you are NOT using CGI.pm then you can
find the technique that is used in CGI.pm
by reading the source code for CGI.pm
Hope this helps.

Oraperl is just a wrapper which calls the DBI API.
See for yourself by reading the code for Oraperl.pm
Hope this helps.

you sound like you're pointing your browser at the perl script sitting in
your filesystem .. you cannot do this
CGI scripts need to be run through a web server if you want to run them
from your browser .. depending on your OS there are probably a bunch of
different freely available web servers .. most likely there's an Apache
port for you
www.apache.org
make sure you read all the documentation
alternatively - if you're using the perl CGI module then in most
circumstances you can run your CGI script from the command line .. and
enter in the name/value pairs manually .. check out your perl
documentation for how to do that .. if you're running the ActiveState
port of perl then start at the ActivePerl FAQ -> Introduction .. and work
your way through

indefinitely? Maybe you should try working with blocking calls. That
way the socket buffer will time out and you should see something
coming over at least every 200 ms. It looks like something may be
sitting in a deadlock at the TCP/IP level.
If I were you, I would post this question in one of the solaris groups
or one of the tcp/ip groups. Solaris's implementation of socket
buffers and nagle's algorithm seems to not really work with the best
default values.
Setting TCP_NODELAY socket options on both server and
client may fix it, and will most likely not cause any dramatic
performance problems.
There's an article out there somewhere about deadlock network problems
like this. Lemme find some reference..
'Deadlock Situations in TCP over ATM'
Kjersti Moldeklev and Per Gunningberg
Altavista should get you a reference to it.
I am not certain that this is what you are seeing, but I've seen
similar behaviour with blocking calls whenever Solaris is involved.

Administrivia:
The Perl-Users Digest is a retransmission of the USENET newsgroup
comp.lang.perl.misc. For subscription or unsubscription requests, send
the single line:
subscribe perl-users
or:
unsubscribe perl-users
to almanac@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.misc (and this Digest), send your
article to perl-users@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.announce, send your article to
clpa@perl.com.
To request back copies (available for a week or so), send your request
to almanac@ruby.oce.orst.edu with the command "send perl-users x.y",
where x is the volume number and y is the issue number.
The Meta-FAQ, an article containing information about the FAQ, is
available by requesting "send perl-users meta-faq". The real FAQ, as it
appeared last in the newsgroup, can be retrieved with the request "send
perl-users FAQ". Due to their sizes, neither the Meta-FAQ nor the FAQ
are included in the digest.
The "mini-FAQ", which is an updated version of the Meta-FAQ, is
available by requesting "send perl-users mini-faq". It appears twice
weekly in the group, but is not distributed in the digest.
For other requests pertaining to the digest, send mail to
perl-users-request@ruby.oce.orst.edu. Do not waste your time or mine
sending perl questions to the -request address, I don't have time to
answer them even if I did know the answer.
