Thanks Rob
All they're saying is that $a = $b doesn't tie $a and $b together in any
way, it just copies the value of $b to $a. If you change $b after that
it won't alter $a again.
Can you please explain me with a sample code. If I understand it
correctly does the below code holds true for your explanation
#!/usr/bin/perl -w
$b = 2;
$a = $b;
print "$a\n";
$b = 4;
$c = $b;
print "$c\n";
Something like that. How about:
$b = 2;
$a = $b;
print "$a $b\n"; # Now $a has the same value as $b
$b = 4;
print "$a $b\n"; # $b has changed but $a stays the same
