Local (Texas A&M - Manhart and Wilson) are developed and updated as MS Excel spreadsheets that carry names (family, genus/species) file names, server directory location, and comments. Simiar data are provied by other contributors to the library, usually as delimited text files. Data files from all contributers are merged and output by the program DFTOUT1 to update the system. This produces a single database (TEXIMAGE.ITB), that is processed on a record-by-record basis to produce an HTML file (IMATX???.HTM) each vascular plant family present in the Texas flora represented by an image. This involves the use of a database containing taxa of the Cronquist classification system (CRONQ3.ITB and indices) for subclass/order strings and another, fullfam1.ITB, for unique, 3-character strings used to create file names. DFTOUT2.IPF takes data from TEXIMAGE.ITB to generate five interlinked HTML pages, starting with families A-B, and this page. The program 'walks' through TEXIMAGE.ITB, generating the listing and links as it progresses through the data table.

We are in the process of 'proofing' base data tables and, as this proceeds, errors evident on these pages should diminish.
