Hi,

I am trying to pass empty/ undef values to a subroutine the following way:

$ret_val = my_sub($arg1, "", $arg2, "", "", $arg3);
And in the subroutine:
sub my_sub{
$arg1 = shift;
$undef1 = shift;
$arg2 = shift;
$undef2 = shift;
$undef3 = shift;
$arg3 = shift;
....... and so on
}

[download]

The problem is that in the subroutine, undef1 gets arg2 and arg2 gets arg3 since other values are undef. Is there anyway I can pass all the values and get all the values from the subroutine in the order they were defined irrespective of whether the value is "null" or Not.

Thanks
