Re: Is it possible to do pass by reference in Perl?

[RedDragon]

It is possible to pass by reference in perl. The argument list u get inside ur subroutine via @_ are implicit reference to values that were passed in from inside from outside.i.e. if u pass in a list of strings, inside the body of the sub,change those strings,then they will be modified outside the subroutine.

sub ted {
my($add,$sub,$mul) = @_;
...
..
}
