Hi Monks,
I have a string of numbers that comes into my program that supposable, it should have 6 digits long, like 123456, but sometimes it will come in to the program with 4 or 5 digits only, when that happens I have to add 0's to complement the string to have 6 digits.
Like if a string of number comes in with 1234, I have to add 0's to it like, 001234, so it can have 6 digits.
I have a regular expression that isn't working but my question is what is the best way to do this?
if($u=~/\d{4}?/){$u=~s/\d\d\d\d/00$u/;}
if($u=~/\d{5}?/){$u=~s/\d\d\d\d\d/0$u/;}

The code above isn't working because in both cases it match the digits it finds.
Thank you!
