hi,

i need a quick oneliner for this script if one exists:


my $array->[0] = $arg{key1};
my $key->[0] = 'key1' if ($array->[0]);

[download]
so basically i have a hash that needs to be broken into two arrays and depending on a hash key the position of the key and value needs to be placed on a specific position in two corresponding arrays

thank you

Update:

ok i have a sub() that takes some variables. and the way to pass some variables to that sub is through hash interface.like this:


sub _sub {

my %arg = @_;

my $array;    # sometimes is treated as a scalar
$array->[0] = $arg{key1};
$array->[1] = $arg{key2};
$array->[2] = $arg{key3};
$array->[3] = $arg{key4};
...
}

[download]
sometimes user can pass only one variable to the _sub(). for example 
_sub(key3 => 'big-mama');

[download]
in this case only the $array->[2] will be defined and all others will be undef. so what i need is one extra array that will tell me the key (key3) that corresponds to that variable and that key should be placed on a $secarray->[2] position
