There's a big spew going on from eunet at the moment.... A silly machine
downloading news, stamping a new message ID on them and reposting them.
You can kill by either the message-id or the NNTP-Posting-Host.
For those using Cleanfeed, keeping this Perlish:
return "duplicate" if $hdr{'NNTP-Posting-Host'} eq 'p8.isdn-brg.eunet.no';

Look at the IDs. Different domain-parts. Me thinks it is some luser-system
that reexports messages with changed IDs.

Hello,
I am having difficulty with this particular object... I am
trying to create or "build" this object from several different modules
or packages.... The problem I am running into is in calling the method
that puts the data into the object. It seems that while I am in one of
these other packages or "subclasses" I can't find my way out to call
the function from the parent class..... the parent class is in @ISA
qw(parent)... I can get it to work if I use $this = Parent->new ...
but that wipes the data in the object.... hmmmmmmmm....
any advice?

Yes. Post an example so we have at least a

Will only be a problem with 32 bit ints on 32 bit CPU's. Isn't a numeric
scalar on, say, the Alpha, 64 bits? It probably will be on every platform
used in 2038. (Unless someone silly with no mathemetical skill
decides that we need 128-bit time_t's or Intel can't make Merced compatible
with the 8088, so Wintel machines never get the volume to make the price
affordable.)

Actually, I do it because it's mindlessly easy to parse and very much cross
platform, so I don't have to deal with converting to network order or other
nonsense in dealing with binary values.
I may not always parse a file for the dates, but by keeping them human
readable, I can grep for other things without spazzing out an xterm with
funky control codes.
I don't worry about fixed length records. Either it's done as a hash where
records can be any length, or it's a pure flat file. Fixed length records
remind me too much of COBOL on punch cards.

Cool. Now, is there a way to print the file name as well? Err... does
Perl keep the name of the currently opened file (for <>) somewhere? I
would expect $ARGV or something.
Eek! That's it! Too bad I can't run this code from the DOS command line.

This means your server doesn't recognise the stated character type or didn't
find the information relating to this, though the content is ASCII (otherwise
this would be unreadable to you) I suggest you ask your service provider if

Umm no. It means I read the docs but didn't find the answer to my situation
and don't have enough experience to make the leap of logic - you do remember
programming 101 don't you? Or did you always know what you know now. Take a

Oh really and where is the beginners class here? I don't recall seeing a
comp.lang.perl.newbie news group mentioned in the FAQ - was this an omission?
Either that or it doesn't exist. I suggest you refer to the
comp.lamg.perl.newbie thread of this very news group to see the doscussion
about why this NG doesn't and probably shouldn't exists

I don't remember having asked anything in my posting, or are you using a third
person plural "you"?
You (2nd person singular) may find FAQ postings boring and annoying but you
(2nd person singular) don't have to read them - this is why you (third person
plural) get to download the subject lines of the postings first. Usually ones
containing the words "HELP" and/or "NEWBIE" are the kind you (2nd person
singular) should avoid reading seeing as how they irk you (2nd person
singular) so much. Other key words are "CGI" or "NEED SCRIPT NOW".
> Hope this offends you
No I don't find your posting offensive, but I do find intollerance and narrow
mindedness rather tiresome. I post the FAR whenever threads spring up in
response to a "guru" flaming some newbie instead of passing it over, see the
currently running "WHY DON'T PEOPLE READ THE FAQ" and "SIGH" threads. Previous
to these there was the "HIDING USER INPUT" thread - (btw have you noticed how
much sweeter Abbigails replies seem to have become since then?) and countless
others before that in the run up to the forming of comp.lang.perl.moderated.
Much in the same way you appear to find newbies annoying because they keep
asking the same questions, I find "guru" flamings bothersome because they keep
flaming for the same reasons and generate an endless quantity of off topic
traffic. News Net is what its users want it to be, and that means all of them,
not just what a vociferous minority insists on, and if that means Newbies
asking FAQs you'll just have to learn to live with it, or avail of the beauty
of internet and set up your own news group where you can ban newbies, maybe
you could call it comp.lang.perl.moderated.no.newbies

Yes!!! But if you do it with matchsticks, it's easier to visualize
than with 1's and regexes.
Take 9 matchsticks. They can be divided into (more than one) identical
group of (more than one) matchsticks.
It's the same thing. Take a string of 9 '1's. Then divide them up
into groups of more-than-one with the regex (11+) Then make sure
there are more-than-one groups (11+)\1+ and then make sure there
is nothing left over /^(11+)\1+$/

Special notice: in a few days, the new group comp.lang.perl.moderated
should be formed. I would rather not support two different groups, and I
know of no other plans to create a digested moderated group. This leaves
me with two options: 1) keep on with this group 2) change to the
moderated one.
If you have opinions on this, send them to
perl-users-request@ruby.oce.orst.edu.
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
