The RPG application places an address and a key it has generated on the request queue. Java reads the request queue and sends the address to Google. Google responds with the latitude and longitude which the Java app places on the keyed data queue with a key value of the key the RPG generated. The response on the keyed queue is read by the RPG.

After downloading the county fip codes from the US Census web site as a CSV file you can utilize them in your program as follows.

Set credentials for using Google geocoding API then get the lat and lang and use DecimalFormat when updating character fields in the database.
boolean failed = false;
static final String key = "get this from google";
static final String id = "get this from google";
static final GeoApiContext context
= new GeoApiContext().setEnterpriseCredentials(id, key);
try {
GeocodingResult[] result
= GeocodingApi.geocode(context, address).await();
double lat = result[0].geometry.location.lat;
double lng = result[0].geometry.location.lng;

Connected to AS400 from Ubuntu running on VirtualBox. node-jt400 fails installing on Windows hence the use of Ubuntu on VirtualBox.
// run on Ubuntu since node-jt400 fails to install on Windows.
