@MyArray = &YourFunction(pass variables here); ## or
$MyString = &YourFunction(pass variables here); ##might work!

--------------
sub YourFunction{
    @array =@_;
    (do something)
    return $YourString;  ##wich ya get a string
    return @YourArray;  ##wich ya get an array, i think the 
                        array objects seperated by spaces!
                       (and furthermore you can change the 
                        space to something else through a 
                        special command to the perl
                        interperter! :P )
    }
