Robert, The coding appears to be appropriate. If you open up the Libraries using SAS Explorer and go to the MAPS, MAPSGFK, and MAPSSAS folderS, you will see all(?) the maps library tables. I do not see the tables named in the book, in the library, however someone could have invented them and written it to the 'sql' library that the code is executing. In my experience, the names in map tables are not "coordinated" and the value in a name in one table could be in a completely different name in another table. Perhaps that is what the author was trying to express.
