      . . .

      But honestly, this is a job for sprintf():


      sprintf "%0${len}d", $number;

      That is, sprintf("%05d", 123) returns 00123.

       Why not (simply)?:


       $string = sprintf( "%05d", $number );

       You can do the same thing with sprintf.


       my $f=sprintf("%05d",123);

       will put "00123" into $f.
