Using -split- was mentioned early in the thread.
Your trick is a nice one. Finding the longest is also possible by
using -length()- or by using the fact that "X", "XX", "XXX", etc. can
be compared using < as "X" < "XX", etc.
In this particular problem, creating lots of extra variables as might
be expected from -split- didn't sound an especially good approach to
me, especially as there are more direct ways of getting at the maximum
and the dataset was relatively large.
It's always helpful to know various ways to approach a problem.
