Yes. Try dejanews (I just did) and search for "pws" limited by this

Or, be happy and download Apache from www.apache.org.

If you don't mind Apache for NT seems to swallow all CGI error

Hi, May name is Rey
I am interested in learning how to build sites, but if I need to
build a "hot mail", "ebay", or "Yahoo"
that includes automated registering with password etc. Do you think
Perl and Unix are the best way to go?
Also, I sold a couple of words (domains) and one of the new owners
is asking me if I know of anyone that could develop them- fleamarket.net
and distressedproperty.net
I advised them to get a Sony Mavica because it seems they know almost
nothing about internet. This should help them email or upload jpgs. and
help a developer.
Can you know some names of books or sites that could help me find scripts
for these site styles? Also, do you do any work on the side and can
you propose some package if I provide the server and info?
Thanks,
Sincerely,
Rey

CGI is not a language. It is an interface to a program in any language
running on a server.
Perl (running in any environment with any interface) has many useful
functions.

Message-Id: <3710b9eb$0$216@nntp1.ba.best.com>
I recall reading something somewhere (in a man page? an O'Reilly book?)
that gave a mnemonic device for remembering which symbols go with which
types of Perl variables:
$ is a stylized 's' for 'scalar'
@ is a stylized 'a' for 'array'
but I can't remember what, if anything, the hash's '%' was supposed to
represent, and I haven't been able to track down the original source.
I have a vague sense that this was Larry Himself promulgating this
wisdom, but I could be wrong.
Anyway, I'm sure there are about 150 people (at least) who will
remember where this came from more or less instantly. If one or more of
those people will take pity on me and tell me where I can look up the
original, I'd appreciate it. Thanks.

Wacky. However, it is very likely that it's actually inherited from

Subject: Help please: Ho do I write a perl app that prints formatted text?
Message-Id: <3710C207.AB25E195@teleport.com>
Hello:
I've posted this query before, but maybe not to the right newsgroup. I
want to understand how printing works, both under Linux and Win9X.
(Well, Macintosh too, for that matter.)
My usual modus operandi is to write a perl app that generates a TeX
file, process that to get dvi, and print with dvips/ghostscript. This
works great on my Linux box with all my customized LaTeX document style
files, but it's not particularly portable.
I know I could also generate html or rtf and let another app do the
printing, but that's not what I want.
How do I write a perl app that sends its output directly to the printer
driver of the OS, giving the user control over the choice of font? I
want to be able to exercise TeX-like control over where the text goes on
the page. I also want to do basic formatting (bold, italic, font size,
etc.), but it would be utterly impractical to duplicate my custom TeX
setup on every installation, especially on Win boxes.
Surely this is a problem that's been solved with perl, but for the life
of me I can't find documentation. Every reference to "print" in the
four Perl books I have (all O'Reilly) is a reference to "printing" on
the terminal, or sending ASCII text to a file. I'm talking about
something that would handle fonts and printing the way, say, Quicken or
WordPerfect does under (arghh!) Win9X.
Clearly I need a primer on how printing works. For example, in the path
from app to driver to printer, what language(s) is the output file in?
Presumably it's in PCL or Postscript between driver and printer, but
what about the prior step, between app and driver? It's all voodoo to
me. Please help me understand this.
There oughta be a book somewhere . . .
Any references, suggestions, pointers to where my query ought to go,
etc., would be greatly appreciated. Please cc to advlach@teleport.com
(if you don't mind).
Many thanks,

Subject: HELP! - A very simple problem, I'm sure...
Message-Id: <7eqgk8$s6l$1@cfs2.kis.keele.ac.uk>
Dear All,
My problem is this: I'm trying to read in a data file which looks like the
following:
head -26.27939 43.58512 14.08601 43.43750
head -26.14723 43.68331 14.11775 40.93750
head -28.55041 48.04858 15.52853 50.81250
head -27.17389 46.06922 14.88883
63.93750......etc.....
This data can vary from 1 entry to an infinite amount. I would like to read
the file in and loop through the set until it reaches the end, reading each
entry (as: text, xvalues, yvalues, zvalues, intensity). My current code
looks like this:
open (READFILE, "$filename") || die "Can't read $filename: $!";
chomp ($text = <STDIN>);
chomp ($xvalues = <STDIN>);
chomp ($yvalues = <STDIN>);
chomp ($zvalues = <STDIN>);
chomp ($intensity = <STDIN>);
print "$text, $xvalues, $yvalues, $zvalues, $intensity";
close (READFILE) || die "Can't close $filename: $!";
This is just a test to see if it can read and write the first entry -
unfortunately this doesn't work!!!!!
Is it also possible to scan the file before hand to find out how many
entries (lines) there are to set up an array size?
Thanks,
Andy

^^^^^^^^^^^
These quotes here are unnecessary.
You have omitted the first few lines of your code which should look
something like this:
#/usr/local/bin/perl -w
use strict;
$filename = 'whatever';
The first two lines are important and will catch a lot of mistakes you
may make.

Ok, you open a file and associate it with the filehandle READFILE, but
here you are reading from STDIN. And you don't have a loop anywhere.
You probably want something more like
while(<READFILE>) {
chomp;
my ($text, $xvalues, $yvalues, $zvalues, $intensity) = split;
print "$text, $xvalues, $yvalues, $zvalues, $intensity\n";
}

"Doesn't work" is not a very helpful description of your problem. In
this case it is very obvious that your code won't work as desired but
you should still describe what your program actually does if you want
help. Choosing a subject that has something to do with your problem
can't hurt either.
> Is it also possible to scan the file before hand to find out how many

This is not necessary. The code I have shown you is quite common and
basic. If you have never seen anything like it before, I suggest you
start reading the documentation that came with perl. You might also
benefit from the Llama book, _Learning Perl_.

Here are some helpful hints which are Usenet stylistic recommendations:
[1] Don't put your response before the text you are replying to.
Answer comes before question on Jeopardy. Usenet is not Jeopardy.
[2] Don't quote everything that was said before.
You should only quote what is relevant and necessary to put your remarks
into context.
[3] Never quote signatures.
You should include an attribution line, which you have done, but nobody
needs to see the sig quoted. This is just a corollary to rule [2].
See how I have applied all these rules above so that my entire message
is readable. Unfortunately there isn't a lot of content here that isn't
available elsewhere (news.announce.newusers) in greater detail.

You might read up on @ARGV. The author of the script didn't help you

No.

You are confused between invoking a program via the Common Gateway

arguments supplied in the latter case.

"man perlvar", which seemed the obvious place to look, no?
And in Learning Perl, including examples that start at p227 in the
edition I have here. A newbie (a serious newbie, anyhow) really should
invest in that book; the quicker they decide they've got beyond what's
covered in the book, the more effective the book has proved its worth,
right? ;-)

Hang on, are you confusing execution from the command line, and
execution from the CGI environment?
The CGI programming interface is clearly defined (and isn't specific
to Perl). If you're programming a CGI, then I strongly recommend
programming to the CGI interface specification, and not relying on
something else that you happen to find hanging around in the
environment.
If you use CGI.pm, then it gives you a comfortable debugging environment
from the command line too. You don't need dual-path code of your own,
in that situation. Program it yourself, and you'll be re-inventing the
wheel again and again.
Apologies if I'm misunderstanding your point.

I'm sick of going to Elvis(vi) then out and typing ./XXXXX!!!! then back to
elvis, and out to command line.
Thanks,

I use VIm
and the syntax highlighting
is acceptable
however
wouldn't it be nice it if kept a module hiearchy in a separate pane, had an integrated help, debugger, etc
imagine Visual Perl
I don't know how anyone else feels about the Microsoft Visual tools, but as far as assistance to editing code, they are pretty good. And I'm sure that Borland's tools are just as good.
Perlbuilder is a good start, but it has a long way to go, and I would like to see a more pluggable interface than any of the Microsoft tools. If I want to use VI as an editor then I want to use VI
I have always wanted to make one, but......well you know, I have to get off my ass. One day though.

For what?
Programming is a way of thinking about problem-solving. What language
you do it in is sort-of secondary.
Of course, people whose first language was Lisp may be expected to think
differently. And it's commonly reputed (in our field) that "physicists
write FORTRAN in any language" (although that's less and less true with
time). Only last month a colleague showed me a program allegedly written
in C++: in reality it was perfectly obvious that it was FORTRAN,
transcribed into a different language, and not really C++ at all, apart
from the surface syntax. But he's an old-timer - like me only more so.
C provides powerful facilities for shooting yourself in the foot,
in all sorts of detailed low-level ways that Perl can shield you from.
Which is not to say that you can't shoot yourself in the foot with
Perl, if you try...
One respected colleague considers that the best way to start programming
is with Java, even though you subsequently migrate to something else for
your "real work". It's the object orientation, you see. I rather
suspect he's right. But it all depends on what you want to achieve.
No language is ideal for everything: if there was, then the others would
all have died out, it stands to reason.
[disclaimer: I wrote my first program in 1958, so I'm too far away from
the problem to have a clear idea how I would want to start again today.]

The answer is: "A hamster, a roll of duct tape, and a Phillips-head
screwdriver"...
Your question is very similar to asking "Which is better to learn to
use: a hammer? Or a drill?": C and Perl are different tools, that
are used for very different purposes (although there are projects where
either would work).
If you're thinking of a career in software, you'll want to learn both.
If you just have some simple "personal" jobs to do, Perl is probably
better. But something like Basic or APL might be better still,
depending on what you have in mind.

]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.
