Use Wordpad, or Notepad, or whatever you want - then
when you upload the script, set your FTP client for
"ascii" mode - this will strip off the "\r" char's.
(that's perlspeak for ^M, or return.)

That is most likely your problem. The last distro of Slackware I used shipped
with a completely broken glibc. (As a former Slackware user, I know. It caused
me no end of problems.) Either compile glibc yourself from source or get a real
Linux distro such as Debian or Redhat that ships with a working glibc.
(Slackware did die several years ago, in case you weren't notified.)

Logically I assume that it is the only one of these modifiers that behaves
this way - but I cant actually remember seeing it documented only referred

Hello,
I have two questions.
If I have an HTML form that has a multiple selection list box, what
type of code do I need to get all my selections? Currently I am only
able to access the last selected option.
This leads into another question. If I need to repost the form data,
including the list box data as hidden fields, how would I do this?
Please send replies to my e-mail.
Thank you for your help.

Note that I did include that I do accept a certain degree of code
reuse...especially where it serves my needs. Rewriting a module to better
serve my needs is a relatively trivial task (no matter how complex that
module may be) compared to rewriting Perl, a C Compiler and an Operating
System for every platform out there.
>A professional programmer tests his code with new releases of modules
>before using them.
Yet *no* professional programmer can ever test his/her code with *future*
releases of someone else's modules... It is called the "future" for a
reason. Think before accusing, please. I can test every past, current, and
beta version of a module available to my heart's content. But I have no
personal control over what might be released by another author in a future
version of *their* module. I also have rather little control over what
version of a given module another user may have installed on their system. I
do have full (or as near as possible) control over my own versions, however.
Unfortunately, much of my audience, CGI users, consists of genuinely novice
programmers (at best, many can not even design a proper HTML page). Imagine
for a moment, if you will, the confusion trying to maintain *multiple*
versions of a single module (We'll call it the ABC::XYZ module to hopefully
not step on anyone's toes) within their personal cgi-bin or cgi-local space.
>I think you're really suffering from NIH syndrome, but won't admit it.
While one of the principle rules of Perl is "laziness" (i.e. reuse), I have
yet to understand why so many are totally shocked when one programmer chooses
to invoke the equally important "there's more than one way to do everything"
rule.
CPAN is a resource, but it is *not* the only way to do things.

No, it's more of an insult to people who are so devoid of a sense of

That's because you only have to register if you actually want to post an
article. So there's no practical need for registering without posting
an article. Duh!
Whereas on a mailing list, you have to register even if you only want to
read the list. Thus, registering for clp.mod is actually *easier* then
signing up for a mailing-list.

Excuse me? I did not say that it forced anyone to read the FAQs. The
registration email provides information *about* the resources available.
And the registration instructions are buried in the message. Thus,
anyone who registers will have read *about* the resources.
Of course, we cannot force someone to read the FAQs, so I don't see why
you're trying to build your argument around that. If someone chooses
not to read the FAQs, that's too bad, but then their questions won't get
posted, so they'll be SOL. The registration process gives them the info
on where and how to get answers, and I'd say that's as much as we can
hope to do.

Why? Because you have to register to post? Waa waa!

You're comparing apples and oranges. You were going to send the post
anyway, otherwise you wouldn't have needed to register.
Actions required:
Read Only Register & Contribute
---------------------------------------------
Mailing list | mail mail+mail
clp.mod | none post+mail
So, it's no harder to contribute to clp.mod than it is to contribute to
a mailing list, and it's easier to start reading clp.mod than to start
reading a mailing list.

This is not a Perl error message - it would however suggest that your
'CGIwrap' is not able to find your Perl script (whatever CGIwrap is). The
problem would be to do with either the configuration of your server or
the request that is being issued to it - I'm afraid that either of these
issues are out of the scope of this group.

I see, one of Matt's notorious scripts . . .
Your error has nothing to do with the script though. Your ISP is probably using
the CGIWrap program to let you run the script as yourself (instead of the server).
Something is amiss there. Your best bet is to ask your ISP (netcom?) about this
(or check their online resources).
(And no, please don't post the source of CGIWrap ;--------------) )
Good luck.

^^^^^^^^^^^^^^^^
Perl doesn't require that. It just calls the OS. Operating
Systems are responsible for managing files.
The _OS_ is requiring that.
If you wrote your CGI program in C, you would have the same problem.

Perl can read a file with those permissions just fine
(try it from the command line).
A CGI program may not be able to though...

Well, the sentence quoted above seems to be spot on ;-)
You don't have a Perl problem.
You are asking in the wrong newsgroup.
Try asking in a newsgroup that has some connection to CGI
programming and/or servers, such as:
comp.infosystems.www.authoring.cgi
comp.infosystems.www.servers.unix

Any script should be able to read rw-r--r-- files as long as the owner of the
file and the script are the same.

Depending on what you want to do, 'sort values %hash' may be what you're
looking for.

Subject: strange behavior of $~
Message-Id: <36907F80.7BE5A75D@mail.nevalink.ru>
Hi,
I'm usually r/w to Perl-Win32 lists but this lettle problem has nothing
in common with Win32.
I'm writing small pwd-checker rather in JAPH (or obfuscated) style. This
sample is a small extraction:
$a ="ba0bc";
$,=97; # ASCII code of 'a'
$a=~s>.>($_=ord($&)-$,)\>=0?chr:chr hex$&>gse;
print $a;
This returns as expected "\x01\x00\x00\x01\x02" i.e. 5 chars.
But when I use $~ instead of $a
$~ ="a0abc";$,=97;
$~=~s>.>($_=ord($&)-$,)\>=0?chr:chr hex$&>gsex;
print $~;
not the same. In fact if no char in $~ evaluates to hexadec 00 -
everything works the same. But in this sample it returns only "\x01"
i.e. it stops when the ongoing character evaluates to 00. I.e. $~
behaves like C-string.
Not good?
I'm using GSAR port of perl 5.004_02 but I guess that small bug can be
still alive.
Thanks and season greetings.

And even more. $>, '$,'(I replaced $,=97; to $.=97), $<, $- used instead
of $~ all return unexpected result. But $;, $: can handle binary data.
$| can be only 0 or 1.
$|=7; print $|; prints 1
Is there any reason that these variables have such a strange behavior? I
see, $| is always used as TRUE/FALSE flag, but there is a clear rule in
perl - what's TRUE and what's false. And "everything is possible that is
not forbidden" ;)
Thanks for any input on this problem.

]It is possible to subscribe to comp.lang.perl.moderated as a mailing list.
]To do so, send mail to majordomo@eyrie.org with "subscribe clpm" in the
]body. Majordomo will then send you instructions on how to confirm your

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

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

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
