in reply to returning tied array

You seem to have discovered that subs return lists, not arrays. I'm not sure why you want a lexical @F; seems to me that if you want to emulate perl's -a switch, you want to set the global @F and $_, and if you don't want to, using a returned arrayref is fine.

But I hope one of the things suggested by others helps you get where you want.

    Hi all, (please ignore the "intermidate" thing) as far as i know, returning anything from a sub, object etc, usualy returns an array, sorry dont have time to check the script, but try, 
    @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 )
    }

      If you return a list from a subroutine, then you get that list back. If it was in scalar context, then you only get the first item of the list.

      You can use wantarray to see what context you were called in.

      Update: s/\barray\b/list/g per chromatic's comment.

        You can only return scalars and lists and (nothing) from subroutines. You can't return arrays or hashes directly, only as lists or references.
