Hello, Given a string:
i994 where I want to replace the 'i' by a '1' the following regex succesfully replaces the letter by a number: s/(i)(\d\d\d)/1$2/; However, given a string: i99o where I want to replace the 'i' by a '1' and the 'o' by a '0' (zero), the following regex fails: s/(i)(\d\d)(o)/1$20/; for the obvious reason that perl looks for a pattern match at bracket set #20, which doesn't exist. I can fix this by inserting a space in front of the zero, like this: s/(i)(\d\d)(o)/1$2 0/; and then using a second regular expression to remove the space, but that somehow seems silly. Surely there is a quicker way to do this? Regards, Thomas Hamann
