The program 'walks' through the data table VASCOR1.ITB, which carries all vascular plant family names included in the current BONAP (July, 1998) database for the flora of the United States, Puerto Rico, and the Virgin Islands sorted alphabetically. This listing has been modified, using the program VASCADD1.IPF. This runs through the original VASCOR1.ITB and checks each 'accepted' Cronquist family name for a 'local' or 'common' family name in the data table FULLCOM2.ITB. This table carries local names developed by the Biota of North America Program. If found, CRONADD1.IPF takes data to the table CRONCOM1.ITB which is merged with VASCOR1.ITB and the latter re-sorted by technical/local name for the run of CROQMAK2.IPF. The program inserts HTML 'form' code into each of 26 family-level pages which uses CGI code produced by Erich Schneider, of the Texas A&M Center for the Study of Digital Libraries and the Texas A&M Bioinformatics Working Group. This allows conversion the selection to an active URL that links to a specific subclass page and internal family link. CROQMAK2.IPF program code is written in the Knowledgeman (PC-database) language by Dr. Hugh D. Wilson.
