If you do not want to replace the character you can set the substring length to zero. `my $padded = 'ABCDEFG'; substr($padded, 2, 0) = '1'; substr($padded, 1, 0) = '2';` [download] This will result in `'A2B1CDEFG'`	[reply] [d/l] [select]

substr($string, $position, 0) = $what_you_want_inserted; where $string = the string you need to have something inserted into $position is where you want to have something inserted (a numerical value such as 0{for the first},1,2,3,4,5,etc) $what_you_want_inserted is what you want to insert in the string $string at position $position hope this helps Originally posted as a Categorized Answer.
