I'm running build 813 on 'doze XP/Home. I want my Perl script to
determine the directory from which it was run. This is equivalent to
retrieving the command line. For example, from a DOS window I type:
>\perl\bin\perl c:\mydir\myscript.pl
I want the script to be able to retrieve the string "c:\mydir".
There is a Win32 function, Find, that can look for files, but it only
searches the INC directories, so it is not reliable.
Any ideas, please.

Newbie should begin writing a simple script in Perl.
Newbie should post the broken code here when you get stuck.

Thank you, this is the most valuable posting in this thread.
People are spinning around with their thoughts, losing "the point"
because of their emotional outbreaks.
Ok, Uri is right in saying that the FAQ explains it well.
But the FAQ also states that you can follow the guideline ... or not.
Uri is writing "perl actually has stronger typing than many langs" and
(in a followup) "perl and other langs".
He is eager to participate in the flame war, shooting against
"non-regulars".
But I miss a statement saying like: "Well, I have mis-typed Perl, but
nonetheless, I defend a correct typing, because it makes sense and is
part of our Perl culture!"

This presents us with a serious problem. When we speak, we cannot
distinguish between capital letters and small letters. So there is a
danger of confusion, if we should tell people "I'm a Perl programmer",
they may make a mistake and think we are "perl programmers". Then all
hell will break loose. So if we say this rather than write it down, we
should be sure to always say "I'm a Perl with a capital P programmer" or
"I'm a perl with a small p hacker". Or, to reduce unnecessary wordiness,
we can carry a card with us when we speak, and whenever we say the word
"Perl" or "perl" in public, we can produce the card and point to the
correct version of the letter with our forefinger.

And then they invest all their life savings into PERL and loose it all,
or something?

Have you tried posting a question about a non-existence language
called C/C++ in comp.lang.c?
Think of the distinction between Perl and perl a clue-meter. We
already know the contributions Uri has made to this group and to my
work with his modules.
When an unknown poster shows his/her ignorance, someone tries to
give that person a hand by providing a correction. The response to
the correction helps us evaluate if it would ever be worth spending
our time answering questions by this person.

Hi, I recognize your claim on this topic, but I do not back your behavior.
You cannot criticize the [pP]erl mis-typing of newbies and practice this
mis-typing yourself in the same news thread (and use such an emotional
wording).

But it's a rather indicator. What is someone wants to be a little
different, even after having read the FAQ? What if they typed 'man perl'
or 'perldoc perl' early on in their Perl life and just went with the
first few lines:
$ perldoc perl | head -n 10
PERL(1) User Contributed Perl Documentation
PERL(1)
^^^^

perl - Practical Extraction and Report Language
^^^^ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This alone should make seeing "PERL" not surprising, weather one has
read the FAQ or not. If various regulars can be different in their own
way, it's rather hypocritical to bare down on not-so-regular people (or
are they... many people might actually be //regular readers//) in this
manner.

No, you can judge someone purely on grounds like that. If someone wants
to write "PERL", whether based on the man/perldoc page for "perl", that
should be their choice. It is unfair to assume they are 'unworthy'
simply because they want to me a little different. Again, some well
known members of this group do things differently as well (Abigail's
non-standard quoting, Uri's refusal to properly use the shift key and
such) yet it's a crime for others to be different in more or less the
same way?

Yes, but "PERL" and "Practical Extraction and Report Language" come fro
mthe man/perldoc page for "perl", how can one get more official then
something's own man page? Are you saying the FAQ for this group, a user
contributed document, as valvuable as it may be, carries more weight
then Perl's own man page?

Yes I have. They are related languages. C++ is based on C. Most people
seem to understand that, while also understanding what sets them apart.
> Think of the distinction between Perl and perl a clue-meter.
But that is just wrong. If the man/perldoc page for "perl" reads like,
$ perldoc perl | head -n 10
PERL(1) User Contributed Perl Documentation PERL(1)
^^^^
NAME
perl - Practical Extraction and Report Language
^^^^ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
then would not someone using it as such an acronym be in fact //more//
clue-ful [sic], having read the man/perdoc pages? I mean can the
FAQ/guidelines, a user created contribution, as valuable as it may be,
really carry more weight then Perl's own documentation?

That doesn't excuse his blatant hypocrisy; he himself uses "perl" when
telling people NOT to use it. Being a contributor doesn't mean one does
not have to follow what they preach.

Perhaps, but the point here is the correction itself is not necessarly
correct. Not if Perl's own man pages and perdoc mena anything.

And just how does one distinguish between "perl", "Perl", and "PERL"
when //speaking// ?
Go type 'perldoc perl' and you will see that any of those forms is
perfectly valid. Are you saying one cannot be considered "precise" by
going according to Perl's own documentation?!? Does this group's FAQ, as
valuable as it may be, hold more weight then Perl's own docs/man-page?

I am sure that in a Java related group people will post remarks if
someone mixes up javac with java (executables).
Also, I am sure that in C related groups people start to ask questions
if you constantly talk about x is an integer and that you have problems
with it.

Because programming is about being very specific and exact. Details do
matter. Calling a warning and error is another classic one (or vice
versa), or just stating that "my PERL program crashed, please help".

IMO a good Perl programmer knows the difference between Perl and perl,
and knows when to use which one.

Yes, and me, who has English as a second language. As long as all those
people don't write ambiguous statements related with the problem/answer,
I don't have a problem with it.

Yes. Look at the subject: perl should be improved. I read that as: the
perl executable should be improved. I have very little to say on that
subject (I am not a perl programmer/hacker)
However, if the subject is: Perl should be improved, I might like to
read it, because, as a Perl programmer, I have my own ideas.

Uri avoids the shift key for one reason or another. Regs here don't
mistake Uri for a newbie, and hence read over this.
The problem with people who use PERL, or perl if they mean Perl, and vice
versa, often are newbies. They increase their change of being taken
serious by getting it right. Or they might be able to get away with it, if
other regs recognize them as someone who knows their Perl :-D.

I tried this test program:
#!/usr/bin/perl
use warnings;
use strict;
my $var;
if (defined($var) && $var ne "") {
print "$var\n";
}
It didn't produce any warnings. When I put in "my $var = 0;",
it printed "0", just like it should. I don't understand
your question. If by "shorter" you mean getting rid of the
defined() test, then, no, you can't get rid of that. If you
aren't sure if $var is going to be defined, you have to test
for it before trying to use it.

... but no, you need a defined-and operator!
I give up, this exercise is futile!
