Program GTX15 performs a match to Precisely Vertex data by returning a nine-byte key that matches the input address to Precisely Vertex data. The nine-byte key consists of:
-
2-byte Vertex state code
-
3-byte FIPS county code
-
4-byte Vertex city code
To work with the cross-reference files, you must be a licensed user of Precisely Vertex products. You must also obtain the cross reference file from Precisely.
GTX15 is called only from the program GTMATCH, simplifying all subsequent calls from other programs or applications.
