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

• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
