Re: passing arrays to subroutines

[BazB]

in reply to passing arrays to subroutines

A subroutine gets it's arguments as an array (@_), so if you do

my @array = (1,2,3,4,5);
some_sub(@array);

Within some_sub, @_ will equal the contents of @array.
However, you probably want to pass the array into the subroutine by reference (see perlref for more):

my @array = (1,2,3,4,5);
some_sub( \@array );

In that case, the first element of @_, the argument list to some_sub, will be a reference to @array.

# an array, any array
my @bunchOfData = ();

# Subroutine: trythis - shows how to pass an array
sub trythis
{
        my @array = @_;
        print "@array\n";

}

# where the subroutine is called to do something with the array
&trythis(@bunchOfData);
