in reply to Padding out strings.

Here's how you could use sprintf(); 

$value = 193;

# Want 6 digits, 0 padded??
$value = sprintf ("%06d", $value);

# Want 4 digits, 0 padded?
$value = sprintf ("%04d", $value);

You get the idea.

    What do you mean, exactly, by the "first answer"? Both vroom's and my answer's define a pad subroutine that you can give a string and a length that you want the padded string to be. They accomplish the end result in different ways, but both work, and neither assume that you must know the string length beforehand.

      Blech. For some bizarre reason, I was thinking vroom's pad was having the length of the initial string passed to it, not the length of the output string. Whip me and call me an idiot.
