Use an appropriate operator:
$number = $string + 0; # add the number 0
$string = $number .""; # concatenation with empty string
But, in fact, it's usually not necessary to do such kinds of
conversions - Perl will take care of it automagically).

This value is NOT the number of elements (or keys), but has to do
something with the internal usage of the hash (see the camel book
for a short explanantion).

In list context a pattern matching using the 'g'lobal option returns
an array of the matched pieces (see also 'perlop' man page).

In this case ("list interpolated into a double-quoted string")
the separator is $" (default: space). (see also 'perlvar')

Here the separator is $, (default: empty). (see also 'perlvar')

Scalar context => only one line

Are you sure ? Works fine here ... ;-)
Remember that indices of arrays in Perl start with 0 (not 1). That's
why your line above gives '1.0'. Replace '[2]' by '[1]' and it yields
'Spc.html' (at least on my machine ...).

Yes, you are right, and I was wrong. To get the key count, you need
to use the keys(%hash) operator in a scalar context.

There's also:
$string = "$number";
which uses the "stringify" op internally, instead of concatenation,
for what's likely a small performance improvement.

This should probably be eslif (defined $pid) so that the exec happens if
$pid is defined and has a 0 value and the error processing will happen if
$pid isn't defined.

In perl,
while (<>) {
chop;
$count{$_}++;
}
foreach (sort keys %count) {
print $_, " ", $count{$_};
}
modeled after "Tabulating the count of some items", old Camel p. 254.
As a bonus, the output is sorted alphabetically.

cheating?? guess it depends on what the poster meant

No it doesn't. It does mean you can read from it with <>, but STDIN is
still
STDIN, which is usually the terminal, not a file specified on the
command line.
However,
foo.pl < infile
would get it into STDIN.

The basic question is: is this a problem specific to Perl? No, it is
not. So the definitive answer will be found in some cgi/http/html
documentation. To give you some direction, you should check the
directives for your .htaccess (or whatever it's called) file and the
POST method.
Hope this helps,

Message-Id: <3497EE36.EE62BA65@hobbes.mitre.org>
Is there a perl module/routine which allows me to interact with
a computer's serial line. Am looking for something similar to the
'cu' command under Solaris2.
Please reply directly to rhz@po.cwru.edu

Subject: Random access read/write possible in Perl?
Message-Id: <678njm$i0g@bgtnsc01.worldnet.att.net>
Is there any way to perform a RANDOM ACCESS read or write in a perl
script? I know how to do sequential reads/writes, but they are far
less efficient in many cases (eg., i want to read only the last XX
bytes of a file)....
Any thoughts?
Thanx

I first learnt to program (apart from a very minor dabble on a TRS80)
with BBC BASIC, so I had a reasonable idea of what a subroutine was,
what an if statement was and an elder brother who refused to run any
code of mine that had a GOTO in..
many years later I learnt enough C to write some programs to do a little
simulation for my PhD. So I got into the habit of chucking almost
everything into subroutines with pretty descriptive names. Still haven't
a clue about memory management.
And finally I got offered a project that would involve learning PERL so
I've grabbed a few books, fumbled my way through a bit and can seem to
get things to work. My dialect ends up being 'C made easy' rather than
something else..
Still haven't a clue about the finer points of programming (like garbage
collection and so on .. just about getting my brain around OOP) but
slowly getting there.

Never tried it. I suppose it would be good for the soul, but then again
so would learning assembler or some such.
The biggest incentive to learning a language IMHO is to have a project
you want to get done. In my case I have learnt everything I know (which
isn't terribly much) by trying to get particular things to work.
Learning style along the way is a bonus, and (from what I hear) probably
important for transfer between languages.
So If anyone can reccommend a good basic Computer Science text that
would bring me from my self taught + half an hour of actual tuition up
to speed on the very basics of program structure and memory allocation
and how the things work once you peer under the hood of a HLL and get to
the machine, I would be more than grateful. (Probably best by email).

Most good *programmers* know many languages. It's not peculiar to
Perl hackers. If you can't pick up a working knowledge of a new
programming language within a few days of exposure, you will die in
this highly competitive industry. So most of us have had to learn to
adapt. :-)

On the Perl Win32 page, their is a description for the use of perl with
excel through the OLE extension. Since Access, is also OLE
Compliant, it would work in a similar manner.( I think) I have not done it
myslef, but I am going to experiment some with the excel
OLE connection.

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.
