Better yet, ditch Netscape and pickup a copy of Apache for Win32. I run it at
work and it works beautifully.
Even better still, ditch NT and get a unix box with apache perl and php.

Ummm...Hello, McFly, Hello? Have you _ever read_ this newsgroup? do
you know what happens here? do you realize that most of advice and
expertise being lent around here is being done for _free_?
I don't about anyone else, but I'm highly insulted by your

You seem to have mistook my point - which is that this newsgroup is
concerned with the perl programming language and those issues
surrounding its use as a programming language - it is not generally
the best resource for those who are looking to obtain (rather than
write ) software. I pointed you toward a more suitable resource where
can be found software of all sorts - where you could actually look for
what you want.
Your characterization of Perl programmers as greedy is obviously based
on a very limited experience of this newsgroup - there are many people
here who devote hours a week ( a day even in some cases ) to helping
others for nothing with their *programming problems* - but will draw a
line at helping people with their *procurement* or for that matter any
part of their other work for nothing. Let me reiterate - this group
is concerned with the Perl programming language not products.
Anyhow *plonk*

Message-Id: <7eimfv$u0@nnrp4.farm.idt.net>
Well, an easy way to fix the <<HERE problem is:
print <<End_Of_Options;
Calculate: (P)roportional band, (T)hrottling range, (A)uthority,
End_Of_Optipns
print "(V)entilation, or (Q)uit :";
Easy eh? Just take off that last line and use a regular print statement.
It's not the most elequent way maybe... but it's the obvious way to correct
the problem. (KISS)
The <<HERE notations sucks anyway. It's great for large amounts of text, but
it totally screws up your indentation for large scripts. You have everything
formatted and perfectly easy to read, then you plop a <<HERE block in the
middle and you end up with a crappy looking script.
I prefer beauty and brawn...

not as a standard it doesn't, but you can tell who is assigned

IANA the (former?) governing body of IP addresses has set aside IP address
ranges for APNIC (Asia-Pacific), RIPE (Europe), and ARIN (North America), so
you may be able to tell from these ranges. But, of course, its not perfect.
Multi-national companies tend to use the IP address range of their home
country. Look at IANA.org, I believe they have a table of address ranges
that are set aside for each registry.
That's about as close as you will get.
I don't know of any perl scripts, but you may want to check out an
application called Visual Route. It's a GUI trace-route utility with some
pretty cool features. It attempt to locate the IP address origin through
finger I believe, and then displays the location on a world map. Very nice
tool.

You apparently fail to understand that there are other browsers (including
text browsers) that understand tables just fine that aren't "the big two".
I'm thinking in particular of w3-mode for GNU emacs, that handles
tables just fine.
Please stop trying to control *layout* with HTML. Think of *meaning*
instead, and let the reader's tools determine layout.
It's not "beautiful" if I can't render it meaningfully. Stop forcing
things down my throat.

Is your goal to communicate or show the world how much fancy crap you
can put on your web page? If it is the latter, I hope you are not
programming for a commercial operation, because you are going to cost
your company money and customers.

Well, let's see. I assume you are on some type of UNIX box. Perhaps in a X

specific place. Would this be another monitor? Seriously if you want

Subject: Help with Perl return value 134
Message-Id: <slrn7gpj98.3gu.stillers@slip-3.slip.net>
Morning.
We are having some trouble with a perl script that aborts in a
non-repeatable fashion with the following text:
Error: Runtime exception^M
[1] + Done (134) ?^M
188 Abort perl^M
The second numerical error (188) is different every time the error
occurs. This error is happening on a perl script called by the
MKS shell on an Alpha-NT.
If anyone can point me towards what this error indicates, or even
an online resource for perl errors I would be most appreciative.
The perl.com documents have proven to be not particularly useful
for this, and my web searches haven't turned up anything of
value.
Thanks.

I think *you* ought to reread the original question and *then* as a
supplementary bonus read the documentation. exiting the program is
the only way to close all open filehandles without knowing the name of
each one and doing close() on each one individually.

It looks like you have a version of Unix where dependancies on
shared libraries are only tracked for executables, not for other
shared libraries. That is, if you build an executable, you can
tell Unix that, when that executable is loaded, it needs to
automatically load libprim.so to resolve symbols like ciSys.
But there is no way to tell your Unix to automatically load
libprim.so when admin.so is loaded.
One solution I've managed on occasion is to rebuild the perl
executable so that it depends on libprim.so, even though it
doesn't use any symbols from it.
Another solution is to build your admin.so using the static
library, libprim.a, though this will cause problems if you
want to build more than one extension that uses libprim.
It might be possible to specify that admin.so be loaded with
"lazy" symbol resolution then call a routine in admin.so that
doesn't depend on libprim.so and that loads libprim.so.
More likely, you could tell Perl to load libprim.so before it
loads admin.so. Doing a quick search in lib/pod finds you can
add a "BOOT:" section to your *.xs file to do this. You could
also do this before calling C<bootstrap> in your *.pm file. See
lib/Dynaloader.pm for hints on how to load some shared library
from Perl code. See ext/DynaLoader/DynaLoader.xs in the Perl
source code distribution to see which C routines you can use
for this in your "BOOT:" section.

: . Honestly, if its SOOOOO difficult to reply without adding

In the hopes that reasking of Frequently Asked Questions
would become less frequent, perhaps?
How does this sound:
"Honestly, if all you are going to do about my taking cuts in
line is to complain about it, why bother?"
??
Pretty silly, I'd imagine.
If a person doesn't _know_ that they are supposed to wait
their turn in line, then everbody else just lets them do it?
I don't think so. They point out that going to the front is
not how it works...
You are not likely to be able to convince society to give up
on the "standing in line" rule, so attempting such is yet
another waste of time (your time this time instead of others
time).
You either stand in line, or take whatever heat society
issues for not conforming.
: Two minutes for someone who already knew the answer.
But Sam's two minutes isn't the only component in the accounting.
Add 20 seconds for each reader to determine that you are
reasking a question that has been answered hundreds of
times before.
Assuming only 5000 clpmisc readers, that is over 27 *hours*
of time wasted on a question that has already been answered!
But that is for only one reasked FAQ. There are 20-50 a day of
those in this newsgroup.
That's over 500 hours *a day* wasted on questions that have
already been answered.
But that is for only one day. There are 365 days in a year,
so this community spends only 182,500 hours a year doing
stuff that has already been done.
This is Not Good.
: What a surprize! Put
: yourself in the poster's position for a change.
If the FAQ entry is not easily findable, then complaints about
reasking them should not be made.
But when the poster uses the exact word needed to find the
answer in their problem statement (e.g. "greedy"), we know
that they just want someone else to have to do the simple
word search for them.
Takes 10 seconds at the most to go search for "greedy" in the
9 FAQ files.
Do it yourself, you may get the answer in 10 seconds!
: At least I read the book and
: tried cases myself before posting.
But the very first place to look, before books, before the
WWW, before Usenet, is the words of the people who
built the perl that you are using.
These are the standard Perl docs.
They are *included* with the perl distribution.
If you have a properly installed perl, then they are already
on your hard disk somewhere. Find out where.
: As for the FAQs that you so fondly refer, I
: get broken links more often than assistance.
Sounds like you try to browse the FAQs on the WWW.
No wonder you don't want to do it. It would take several minutes
to do a word search over 9 FAQ files that way.
So don't use such an inefficient method.
Access the local docs on your HD.
: The insults and slurs I can do without.
Then stop taking cuts.

Well, after 6 months, here's the answer to the quiz: what do we do about
comp.lang.perl.moderated. Answer: nothing.

]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
]subscription. This is provided as a general service for those people who
]cannot receive the newsgroup for whatever reason or who just prefer to
]receive messages via e-mail.
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.
