taking a stab in the dark - I imagine that the information you require
will be found in the FAQ section entitled "Web Server Config" in which a
question entitled "How do I use ActivePerl under Apache?" is asked and
answered
you will find a link to the documentation on your Windows98 Programs
menu in a section entitled 'ActivePerl'

I see some other people have suggested a couple of different methods but
I think this method is the simplest:
format STDOUT =
^<<<<<<<<<<<<<<<<<<
$blah
.
$blah =
'http://www.blah.com/sjkdhcvb/sdc/sdc/sadca/sa/scsd/cs/acq/awq/da/wdas/cas/cas/csa/cas/csda/cads/csadc/sdacsadc.html';
$: = '/';
write while $blah;
(Thanks to Tom C for expanding my horizons).

yes - my Perl 5.6.0 on NT4 works perfectly well - including the
situation you specifically mention above (except I don't have cygwin -
but rather have installed other ports of various UNIX commands)
I received no such error when installing Bundle::CPAN

I have no idea what that means. Perl comes with manpages. If you
don't have them trivially available, then you don't have a proper
installation and should immediately fire your system administrator
for gross negligence.
See "Pass by Reference" in perlsub(1) for most of this.

Now wait a darned minute, I resemble that remark. I'm one of those
system administrators whose firing you are advocating. I have lots of
systems that have the perl command processor but no perldoc and no Perl
manpages, because that is the way the OS comes from HP. I'm not
suggesting these can't be added, but I think gross negligence is a bit
of an exaggeration.

If it's a vanilla HP install, it may very well have a carcass of a camel
(version 4) rather than a live, breathing one.
I think in that case you keep your job; we ought to start sacking people
at HP who think it's funny to package a buggy, eight year-old version of
software that they can acquire for free.
Come to think of it, my latest AIX machine had a ksh that wasn't even
ksh '93 compliant...

Why? Did you install an incomplete perl? (doesn't sound like it)
The docs install by default. To get perl installed without
its docs requires explicit action. Somebody somewhere
_did something_ to cause the docs to not be there.
Come to think of it, that does NOT sound like "negligence".
That has passive connotations, and there was some active
foolishness at play here.

Sounds like someone at HP should be fired though.
I'm not a SA, but if I administered HP machines, I would by now
be giving serious consideration wiping out the provided perl
and reinstalling a complete one.
I do this as a matter of routine when I upgrade my Linux OS.
Perl is too important to me to leave the important decisions
up so somebody else. (particularly after having discovered
such a strange decision as withholding a program's documentation.)

It is clearly gross negligence, _who's_ negligence seems
a bit murky though :-)

Once, when I needed to parse very large weblog files (>10MB), I found

I have searched as many FAQs as I could find, but no simple answer comes
up. I am running perl from (don't laugh) DOS on a PC. What I want to do
is issue a prompt for input, read a line of text from the keyboard,
terminate it with "Enter", and then proceed to do something with the
input.
I can do that in a bunch of other languages, but perl has me stumped.
AFAK, there's nothing in the Camel or Llama books. Am I wrong? Why is it
so mysterious? And most of all, how do I do it?

See Image::Grab in the CPAN for a generic solution, or look at

How is that ethically questionable? I *do* that from a cronjob and have
it mail me the cartoons every day because I can't stand waiting for the
page to load. If they only want people to read the pages online I'm sure
there are ways of making people do so. Last time I looked I'm sure I
didn't see any notice saying 'You can only look at these cartoons
through a web-browser such as netscape or explorer'.

Often they are the URL variety which would send your browser to a

I think MICQ could probably be driven to do something like this from a

Unfortunately I cant use the {..}-notation on my problem, cause I read and
parse from a configfile, so its more like this:
sub a1 {my $line='$s=8;'; eval $line; warn $@ if $@;}
Writing 'eval{$line}' here dosnt solve my problem and I get a warning too:
$> ~/bin/test.pl
Useless use of private variable in void context at /tmp/pack.pl line 9.

It seems I am doomed. I dont want to use 'our' instead of 'my' do prevent
the packageuser from doing ugly things and I cant add dummy-statements
like '$s;' or '$s=$s;' in the sub, cause I dont know which variables will
appear to evaluate and calling the variable a second time inside an eval-
block again of course wont help :-(

However, if the documentation is wrong, it seems that there is no direct

^^^^^^^
You should probably just have said something like: Here's a program I
adapted from the docuemntation of Image::magick. It uses constructs I
copied that I don't understand.
It really pays off to be as precise as possible when you are dealing
with programmers. Programmers need to be professional pedants. You can't
afford to be imprecise when you are a programmer. When you are, you
detract meaning from what you are saying. Pedants, like me, will focus
on that. And, like I said, many programmers are pedants.
When we say that 'I wrote' something, we do mean that we did that. We
don't mean copied bits and pieces and stuck them together. That isn't
writing a program. It's sticking pieces together. The verb 'to write'
among programmers means more than cut'n'paste.

Dear Mr Pedant
You are perhaps the only one in the whole wide world that does not pinch
code from books and software documentation. When I say I wrote, I meant I
take responsiblilty for it, not credit. If I have to mention every person
who should be credited for making the program work I'll have a long list,
starting with Bill Gates.
Thanks for your kind advice. I'll ask you more when I need it

You can take this sort of advice any way you want to take it. But be
prepared to deal with this sort of stuff each time you're not precise
enough. Because...

You can't stop pedants from giving advice.
BTW, please, in the future, post your replies _after_ the suitably
trimmed text you reply to. It makes the threads easier to follow, and is
the commonly accepted quoting style on this group, and Usenet in
general.
Thanks,
Martien

Even I did that! It took no time at all...in fact, most of the comics from
United Feature Syndicate are at http://www.toao.net/comics.pl
It does, however, take a #@$% of a long time to process (about 35 seconds
or so, depending on the time of day I've found) and some of the images are
broken. That's my fault.

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.
| NOTE: The mail to news gateway, and thus the ability to submit articles
| through this service to the newsgroup, has been removed. I do not have
| time to individually vet each article to make sure that someone isn't
| abusing the service, and I no longer have any desire to waste my time
| dealing with the campus admins when some fool complains to them about an
| article that has come through the gateway instead of complaining
| to the source.
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.
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.
