Program for the Macintosh that produces keyword-in-context concordances of words in a text. It can handle both ordinary flat text and multiple-line interlinear text. In the case of interlinear text (produced by IT), it can concord morphemes and also correspondences between two annotation lines. Conc can also do letter concordances to facilitate phonological analysis. Conc permits the user to limit the concordance to just those words that match a specified pattern (GREP expression).
