Hi! I'm trying to make a routine to make a Morris Number Sequence. (http://www.ocf.berkeley.edu/~stoll/number_sequence.html) I need to split a string in the following way, for example. "111223133" => ["111", "22", "3", "1", "33"] I can loop thru the string by each character, comparing with the previous character. But is there a quick and easy way? Probably a regular expression? Thanks. Sam
