Something tells me that the webmaster will repeat the policy about CGI
i.e. either it is banned or that they charge x amount of cash to check
it before it goes up.
They will say that this is to protect the server from newbies that can
do silly things in their scripts.
However I think that this is enough on this, go and read Tad
McClellan's post on better newsgroups to ask in.

Yes it is. Now, go find a more appropriate newsgroup, or ask the
receptionist where the office of your sysadmin is. Your sysadmin
can tell you how to make a file executable.

Bullshit. It's still *NOT* a Perl question. It is however, a financial

Browsers are totatally oblivious to the fact there's such a thing as Perl
in this world. It's *NOT* a Perl question.
() So, my question was:
() is it possible to make it run (somehow) even though its name

Various people already said yes, and pointed out the fact this is not
the appropriate place to ask. What else do you want? Someone to come
over and bang your head on the keyboard till the file is executable?

not necessarily. they are actually different animals, each with
advantages. fastcgi apps can run on different machines which is a major
speedup win rather than having all perl apps run on the apache
system. fast cgi can support any language with a fastcgi module
(perl,tcl, c, etc.) which can be important. mod_perl has access to all
points of the http request whereas fastcgi still just a cgi like
interface. so this is not a good comparison unless you look at the
entire system and its needs. they each have their place in the web.

Sure. Read this:
In perl built for threading, $_ and @_ are lexical. Basically all
this means is that you you can't local() them. In all other ways
they act just like they do in non-threaded perl.
There's a lot of magic attached to $_ and @_. They're just barely
lexical, and they may get switched over to per-thread globals at some
point. (Most of the globals already are per-thread, but $_ and @_ have
huge amounts of magic attached to them already so it's not quite as easy.
Plus $_ and @_ were the first globals to get dealt with, so the
implementation is really first generation, while the one handling $/ and
friends is second gen.

Reading the documentation never hurts. Splitting on /^/ is an undocumented
feature. If you have Ilya's patch, it becomes documented and deprecated:
=item split /^/ better written as split /^/m
(W) Implicit translation of /^/ to mean /^/m in split is deprecated.
I don't know if the patch made it in though.

Subject: Subst. Vars from Readin Txt-File
Message-Id: <37925EFA.95B1657E@arweb.de>
Hi there,
I'm programming a web shopping system and trying to outsource a
configuration file.
But this configuration file also consists of $skalars that are readin as
barewords,
like $line = 'it does not $mind what'; and $mind is not substituted by
the value of $mind.
So I want to make it work like $line = "it does not $mind what"; and
instead of $mind
there is a value like "hello" or "123".
Thanks in advance,
Florian Arndt

Well, that's not *entirely* true. No matter how much memory I've got, perl
won't allocate a scalar larger than 4G. Whether that's a sane thing to do
is another question entirely... :-)

Sorry guys, I ment to post this under my first question. But it didn't
work! I'm VERY new to Perl, but that was just a dumb mistake! The subject
of my first post was "HHHHEEEEELLLPPP" I'm not gonna repost it, because, I
don't really want to get flamed about it. So if you can help please look at
that. Thanks alot!

Message-Id: <null>
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.
