Abstract: Codes play an important role in the study of the combinatorics of words. In this paper, we introduce pcodes that play a role in the study of combinatorics ofpartial words. Partial words are strings over a finite alphabet that may contain a number of “do not know” symbols. Pcodes are defined in terms of the compatibility relation that considers two strings over the same alphabet that are equal except for a number of insertions and/or deletions of symbols. We describe various ways of defining and analyzing pcodes. In particular, many pcodes can be obtained as antichains with respect to certain partial orderings. Using a technique related to dominoes, we show that the pcode property is decidable.
