We can compare any substring at any position in a given string using compare(), which otherwise requires the long procedure of word-by-word extraction of string for comparison using relational operators. If all the columns are PDLs, you can add extra dimensions to make threaded collections of curves. Each column must be a separate PDL or an ARRAY ref.
