Well Bhate, it seems that your not-so-welcomed sort of behaviour isn't so much welcomed after all. I know how user should behave in this list but saying that, let me also mention that if you are of no help, you are of no use. Go read Larry's text (Perl programming), Randal's text. If you don't know what you are talking about, please don't even bother. If you have time to be rude, then you do have time to be polite as well. Tell them to do their homework politely. In the case of OP's question, one way of doing it would be using sockets. I do not have time nor energy at this point to say how they communicate. Have a look at IPC concept. Especially each of your code will open a socket (address + port) and send/listen for data. Then process that data accordinly. You could use LWP threads too if you have huge amount of data to be processed. Hope that helps.

use File::Path qw(rmtree);

If the directory has read-only permission shouldn't the program report
read-only directory. Can't delete ! or something without having to
explicitly die?? Are the semantics heading the right way here?? It
seems rmtree is doing 'chmod +wx' or something here before deleteing
the dir/file, is it right or is it implementation dependent via the
programmer?

Amongst many other things just to name a few advantage of being Roman are u almost never might need to delete messages and the contacts are pretty easy to get around, short cut key etc.. 1000 mb to use as ur own sec storage space. Its pretty good. I feel great!

Re: Becoming Disenheartened - Everyone talks about Python and says Perl is old news.
Perl is more powerful. Python is simpler. Python is for people who don't want to master a language -- just use it casually. This is no serious statement. Python is simple and power too. Read please Bruce Eckel why he left Perl and came to Python. At least, it's really object-oriented as against Perl and it has more funny syntax :). Perl has OO support. In my opinion those funny syntax get u the job done quicker when your boss comes down to you with deadly deadlines. ~;-) I assume those syntax u are talking about is regular expression. -- Best regards, Nicolay http://www.soft411.com - Excellent soft archive http://www.spamliquidator.com - Kill spam [snip] -- Cheers, SanoBabu -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/ http://learn.perl.org/first-response
how do i describe a perl user?

Re: difference between @_ and shift

Hi all, I'm having a look in to object oriented perl. Can anyone tell me
what the difference between @_ and shift is? As far as I know there is no
Straight from the Llama :
@array = qw /dino fred barney/;
$a = $shift @array; # $a gets dino, @array reduced to (fred , barney);
difference except shift removes the parameter from the @_ array so if you
were to shift all parameters passed to a function nothing would be
containted in @_ is this correct?
@_ variable is local to the subroutine. It stores argument to a
subroutine. If u keep on doing shift inside a subroutine then @_
will be empty will become uninitialized again.
sub test {
#$a = shift ;
my $a = shift @_ ;
print $a;
my $b = shift @_;
print $b;
}
test(1);
-perl -w test.pl
-Use of uninitialized value in print at test.pl line 9.
1
But this doesn't in anyway affect the @_ variable outside the
subroutine if there happens to be any.
I'm asking because I'm a little confused about using it. Why can't I do
this:
###
sub nickname {
my $self = shift;
return $self-{NICK};
}
###
[snip]
$self looks alot like this in Java.. no? :)

Re: difference between @_ and shift
So. In the context of subroutine arguments, you're generally passing in one or more arguments. If you're only passing one, then you're right -- my $arg = @_; So what wiggins saying, here $arg has now 1 ? my $arg = shift; here $arg has now the value of the first element(argument) ? my $arg = $_; here $arg gets default value? -- are all equivalent. I agree. :) [snip] -- Cheers, SanoBabu -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/ http://learn.perl.org/first-response
Re: difference between @_ and shift
Ha, didn't even notice that one, yep $_ is definitely different than $_[0], which is what the others would have. -- are all equivalent. I agree. :) ?? You are agreeing that they are, or aren't?
