Hi All,
How do i know the full name of a variable from its reference??.
Say i have a routine defined like this:
package Bar;
sub foo {};
And then i say:
my $x = \&foo;
Now from this coderef ($x) i want to know its fully qualified name which would be
somthing like Bar::Foo.
Is there a way to

I guess by extension you mean that you are trying to subclass a module. In that case
you would need to inherit from that parent class with something like:
our @ISA = qw(ParentClass)
or
use base qw(ParentClass)
Then you can call the methods of the parent class on the instances of this subclass
Maybe OT. But just curious. What do the experts say about exporting function from OO
modules??.
Everytime i need something like this, i end up making those functions as Class methods.

One way:
To find out elements which are in test2 and not in test1:
#!-*-perl-*-
use strict;
my @test1 = qw(1 2 3 4);
my @test2 = qw(1 2 5 6 7 8);
foreach my $element(@test2) {
print $element if([EMAIL PROTECTED]);
}

Look for the removed "()" around the declaration for sub, and u won't tell the sub

I think u would need the "grep" function here instead of "map".
Map returns the results of the evaluation of expression which is '1' in ur case
because u matched.
Grep returns the actual elements of the list for which the expression was true.
try:
my @ptrRecords = grep{/.*\s+PTR\s+.*/[EMAIL PRO
$! is the oserror.
$@ contains the exceptions thrown by eval.
