The Language Analysis Package (LAP) was developed by the Southwest Regional Laboratory (SWRL) to assist researchers in the analysis of language usage. The function of the KWIC (Keyword-in Context or Concordance) Module of the LAP is to produce keyword listings from the input text being analyzed. Such listings will contain location information broken down by document identifier, page, paragraph, and line. Other design features are presented in this document together with the file layout specifications of the program's output. (DGC)
