Thank you for a reply.
I did as you advised, my printed statement after executing the script looked
like this:
SELECT ad_id FROM help_wanted WHERE ad_id in(".join(',', 24 23 22).")
but it didn't select any records. I got the result as 0E0 for number of
found ones??

What does the underscore exactly do, when using _var?
Example:
package Person;
use Carp;
our $AUTOLOAD; # it's a package global
my %fields = (
name=> undef,
age => undef,
peers => undef,
);
sub new {
my $that = shift;

Sorry for bothering all the time, hope you guys don't mind.
What's the use of { # code here # }. I thought this would be intentionally
used for complex code constructions. Do you agree?

My last question... It's getting a bit too much.. I'm sorry for asking so
much.. But I find it quite hard to understand the map() function. Can
anybody explain this?
Again, apologise for asking so much. But I'm just a 14 year old Dutch boy so
sometimes it's a bit hard to follow the English refe
This should have been interpolated, and you shouldn't see the join??
Maybe spaces are needed between the dots.
$query = "SELECT ad_id FROM help_wanted WHERE ad_id
in(" . join(',', @id_set) . ")";
Should print to be:
SELECT ad_id FROM help_wanted WHERE ad_id in(24, 23, 22)
Where the list inside
map takes a code block or an expression and evaluates it for each element in
a list
for example...
my @arr = (1,2,3,4,5);
my @arr2 = map {$_ + 3} @arr; # notice no comma
print "@arr2\n";
4 5 6 7 8
So, each element of @arr had 3 added to it.
Another example, using an expression would be

Quite. Whenever you need to create an list by performing an operation
on every element of another li
It's also worth noting that it can modify your original array in place
@a = ('bob','jane');
map {$_ = ucfirst($_)} @a;
This can be useful (or painful if you forget about it).

True, but I think this is more suited to C.

No. It doesn't
hi all,
my script:
#!/usr/bin/perl
use strict;
print "first line\n";
system ("ls");
print "last line\n";
how can I output "first line\n" and "last line\n" to
the screen but save the result of system command "ls"
to a file(eg "result")(not appear on the screen")?
thanks
Stan

Hello all,
I wish to write a small parser which will seperately file attachments
coming to a particular email id.
Which is the best module to read a mail from STDIN and create a MIME
object so that I can save each attachement in a seperate file
Thanks
