The $1 $2 etc variables *only* have their values outside the regular
expression. Inside the regular expression, you have to use \1 \2 etc.
(You can interpolate $1 $2 etc in a regular expression, but they'll
still have their values from the previous successful match at that
point.)

Subject: Changing case local-specifically
Message-Id: <Atyh3.82$xEh.179233792@news.frii.net>
I'm trying to change the case of a string. That is, "Jack" would
become "jACK". Here's my first attempt:
$_ = "Jack\n";
tr/a-zA-Z/A-Za-z/;
print;
Of course, this will fail for non-ASCII letters such as ö.
This seems to work:
use locale;
$_ = "AeÎö\n";
s/\w/$& ne uc($&) ? uc($&) : lc($&)/ge;
print;
I don't like it. It executes code for each \w character found,
which can't be too fast. I'd like to do one whopping tr for the
entire string, but constructing the tr and eval'ing it would be ugly.
Any ideas?

Yes. Use -w and 'use strict;' to get an actual Perl error. It's kind
of rude to expect a newsgroup to debug your code if you don't even

Hi Hemant
I'm assuming you can look at the file and see but you want the file to
read it itself, or have Pearl read it.
I know that VBA in excel can do that if you need or can use the
excel file itself to do it. Or have another file that will read any file
that you point it to. If so, I think this will help.
Sub count_sheets()
Dim sheet_total
sheet_total = Worksheets.Count
MsgBox sheet_total
End Sub
Remember there may be modules Dialog and chart that can
be counted by taking the "Work" out of "worksheet".
Hope that helps or gets ya closer.

I am currently working on such a document. I've taken your email address

Speed is really dependent on many different factors so benchmarks aren't
always reliable in giving you good information for your specific
situation. What architecture? What platform? What webserver? Ram?
Filesystems? etc. These all count in the benchmark process. Also, it
depends on how well you write Perl. CF could beat out a poorly designed
mySQL database coupled with suboptimal code.
One argument I am making for Perl in these situations is that mod_perl
apache is far faster than Netscape Enterprise with CF on the Solaris
platform. Also, CF adds a layer of complexity as it is a 3rd party bit of
software that hides the workings of it from you so that when you have real
problems, you waste precious time trying to track it down and then have to
deal with the usual tech support gibberish. You are owned by and tied-down
to a single solution, possibly even after the company has folded and
support is no longer available.
With Perl, either you or someone you know (or did) wrote the code and have
a much better chance at pinpointing the problem. Also, a plethora of
documentation and a community that responds to questions far faster than
any tech support line I have ever seen. Perl is also more flexible when
you need to add features. And Perl is here to stay.

However, the authors were able to make something as dry as a

Subject: Use of uninitialized value
Message-Id: <19990709214849.23278.00012781@ng-bh1.aol.com>
Here is the part of my script that reports the error:
(3)$input = 'Steve';
(4)
(5)while () {
(6) chomp($input = <>);
(7) if ($input ne '') {
(8) <snip>
(9) }
I get feedback saying that there was use of uninitialized value at lines 6 and
7. I looked this up in the perldiag and it said to avoid this, assign a value
to your variable. Isn't that what I did when I said $input = 'Steve';?

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.
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.
