in reply to Best method to eliminate substrings from array

Each string is a set of two or more values separated by pipes ("|"). ... eliminate any strings that are substrings of other strings ...

What's a "value"? Can you have a string 'AA|BB|CC? If so, is 'A|B' a valid substring of it? (This would be true if testing with index.) Basically, I don't understand the concept of "substring."

    The values are actually part numbers so they might be something like 124182 or 3718317. The strings are lists of parts that are related to each other and when I generate the lists I might get a string of five parts and then another string containing those same five parts plus one more. I would want to only keep the string with the six parts because the five part string is essentially a substring of the six part string. Instead of substring you could say subset.
