Thanks again The string being matched in the explanation at that link is 'abcbd', not 'abcdb'. The 'a' in the pattern matches the 'a' in the string, the '[bcd]*' in the pattern matches the 'bc' in the string (with a repeat count of 2), and finally the 'b' in the pattern matches the 'b' following that in the string.
