Re: How to declare arrays and scalars together?

in reply to How to declare arrays and scalars together?

As such, nothing looks/IS wrong in your code. It's just that it does not work the way you are thinking it would.

 my (@arr1, @arr2, $var, @arr3) = ( (1,2),(11,22),"0", () );
 print "\n[@arr1]";
print "\nvar is $var";

RHS of first line is flattened into a single list and copied in its entirety into @arr1.
All other elements in LHS of first line are empty. Remember why you can not pass multiple arrays to a subroutine?

"Remember why you can not pass multiple arrays to a subroutine?"

except, one uses reference like so:

my $arr1_ref = [ 1, 2, 3 ];
my $arr2_ref = [ 10, 9, 8, 7 ];

load_arr( $arr1_ref, $arr2_ref );    ## load multiple array references

sub load_arr {
    my ( $arr1_def, $arr2_def ) = @_;

    print join "\n", @{$arr1_def}, @{$arr2_def};
    return;
}

You're passing array references there, not arrays.

That is my point. It is possible to pass multiple arrays, using array reference.
