Re: multidimensional array assignment

@str=@temp;

This is a shallow copy. @temp is an array of references to
arrays. After the copy, @str will contain references to the same
arrays: @str and @temp are different arrays, but $str[$mm] refers
to the same array as $temp[$mm] does. So, when the next iteration
modifies $temp[$mm][$l], it is also modifying $str[$mm][$l].

I suppose the easiest way to construct new second-level arrays is:

@str = map [@$_], @temp;

If you want an even deeper copy, the Clone module might do the job.
