Hi, I am referring to http://www.gnulamp.com/perlscalars.html
$a = $b; # Assign $b to $a Note that when Perl assigns a value with *$a = $b* it makes a copy of $b and then assigns that to $a. Therefore the next time you change $b it will not alter $a. I did not understand the Note:- Can some one make me understand this statement with examples and also what i understand from the below statements( I have added in the comments), is it correct. $a += $b; #is it $a = $a + $b; $a -= $b; #is it $a = $a - $b; $a .= $b; #is it $a = $a . $b; Thanks again Thanks and Regards Kaushal
