Hmmm -- it's not strict compliant, consume O(n) stack frames,
increments $m when not required and isn't properly functional.
Why do that when you could simply:
#!/usr/bin/perl -w
use strict;
print +((sub {
my $f = shift; # Yow!
sub { $f->($f,0,@_) }
})->( # Warning: emoticon line of code
sub {
my $f = shift; # Useless comments follow
my $m = shift; # $m is the number of monkeys
return "array had $m elements\n" unless @_;
shift; # Out, out damn spot!
@_ = ($f,$m+1,@_); # Increment $m
goto &$f; # Tail recursion with Perl
}
))->(1..10)
__END__
Note the beauty of the functional approach. No values are ever
modified, it is tail recursive and consumes a constant number of
stack frames. And it is heavily commented to aid the reader.
Don't forget the special emoticon line, either.
And if I ever see someone write production code like this...
Lambda-calculusly yours,
Tramm

Similar to the one who use some special hashes:
%a = (a=>'b', b=>'a');
%copy_of_a = (keys %a, values %a); #works only for very few %a
You can have a lot of code working correctly given the right test values

Bzzzt!
You have an off-by-one error there.
----------------
#!/usr/bin/perl -w
use strict;
my @arr = qw(zero one two three);

Not all that funny. I have seen posted in this newsgroups 'tests' that
used lists like (1 .. 3) in situations like this. When I tested it
before posting, I made sure to use (4 .. 6). :-)

Even if written without the superfluous quotes on $#arr, that produces
the value of the last index into the array, which (barring obscene
changes to $[) is one less than the length of the array.
print @arr . "\n";
But don't replace the concatenation operator by a comma, because then
you get list context, which produces the contents of the array, not its
length.

Unless you've changed the contents of $[, that does *not* print the number
of items in the array. Did you try it before posting it?
perldoc perldata:
If you evaluate a named array in a scalar context, it
returns the length of the array. (Note that this is not
true of lists, which return the last value, like the C
comma operator, nor of built-in functions, which return
whatever they feel like returning.)

Referring to the array itself in scalar context gives you the length:
if (@MyArray > 5) {
print "More than five elements\n";
}
To force scalar context or make it explicit, use 'scalar (@MyArray)'.

Put the array into a scalar context:
$num_items = @myarray;
$count = ($item1, $item2, $item3); # $count = 3

Where did you get that idea? I'll borrow this from Malcolm Ray's post
in this thread:
perldoc perldata:
If you evaluate a named array in a scalar context, it
returns the length of the array. (Note that this is not
true of lists, which return the last value, like the C
comma operator, nor of built-in functions, which return
whatever they feel like returning.)
In addition to producing two warnings from '-w', your code produces the
value of $item3 for $count. How do I know? I tested it before posting!
It is really a good idea to test *everything* one posts here, no matter
how 'obvious' it may seem. It saves one loads of embarrassment.

Actually $#arr gives the index of the last element in the array,
and the number you will get this way is NUMBER_OF_ELEMENTS-1.
(In other words, if $#arr is "0" this means that you have 1 element
in the array)

I count 4 assignments in your piece of code, hardly what I call

Subject: linking to perl script to html page.
Message-Id: <38177775.E4DEE683@ccrs.nrcanDOTgc.ca>
Hi,
I want to make an existing html page a derived-cgi page, however, I
don't want people to update their links / bookmarks.
The page lies at localhost:/http/docs/index.html
I would like the address to stay the same, but for the file to point at:
localhost:/http/cgi-bin/index.pl
..without a redirect, without the user knowing.
Can this be done?
I've tried ln -s, but the output page shows the perl scripting in
addition.
Any info would be valued.
..Tom

The investment in learning x?emacs is well worth the rewards you will reap.
Beside occasional trouble with cperl-mode in xeamcs, I find it incredibly
useful.

Message-Id: <7v6klu$m1o$1@nnrp1.deja.com>
Hi everybody,
I've been browsing thru this NG for a script that meets certain specs,
but I can't seem to find it.
I'm looking for a script that meets these demands:
People need to fill out a form in wich they make 1 entry, a 6-digit
number. The form needs to send this to a database file and contain
these, delimited additional items:
Article-ID
Article price
Date
Time
IP Address of sender
Many thanx in advance to anyone that can help out.

Subject: Looking for survey script
Message-Id: <7v1nll$pbt$1@bnews.gigabell.net>
Hi all,
I'm looking for a really good survey script. The ones I've found at
www.cgi-ressources.com and similar sites are very simple regarding the
online presentation of the results because they don't allow to put questions
into a relationship. To explain myself. With all these scripts it would be
impossible to generate a result as
"43% admitted to own an eyebrow. 24% of the eyebrow owners said they had a
brown eyebrow; 2% had a blue one... More tha the half of those who don't own
any eyebrows indicated that they are willing to buy one within the next
three months..."
This kind of evaluation would mean that answers have to be stored as one
dataset per person. Of course I could modify any database script as woda or
Selenas DB Manager. But if anybody already has done so, I wouldn`t bother
NOT to have to reinvent the wheel :-)
Any hints are greatly appreciated.

So it sounds like you want to take the script you have already
found, and add on something which takes your script and does
some basic cross-tabulations and/or descriptive stats. Such
modules are already available at CPAN [www.cpan.org] so you
can get them and add their functionality into that script.

Okay, then I suggest you do not use anything written by
Selena Sol. Get some decently-coded Perl instead.

Tom,
as I stated in my posting, I've posted my question here because:
[x] I've searched all those freeware and shareware archives withour success
[x] I'm not precisely wishing to, but (in the worst case) prepared to write
this advanced survey script myself (and make it available to others), if
nobody else in this NG has done so up to now.
ok for you?

If you're wishing merely to _find_ (as opposed to write) programs,
this newsgroup may not be the best resource for you. There are many
freeware and shareware archives which you can find by searching Yahoo
or a similar service. Hope this helps!

You should ask web-specific questions in a newsgroup that
has something to do with the web.
clpmisc is not such a newsgroup.

Administrivia:
The Perl-Users Digest is a retransmission of the USENET newsgroup

To submit articles to comp.lang.perl.announce, send your article to

To request back copies (available for a week or so), send your request

where x is the volume number and y is the issue number.
For other requests pertaining to the digest, send mail to
