Trying to GeoCode multiple addresses

[henryp...@gmail.com]

Hi there. I have looked around and decided that it isn't feasible to
try and geocode multiple addresses...
I have checked out Mike Williams great tutorials - especially for the
mulitple geocoding and using a delay.
The issue is that I don't entirely understand his code as I'm
inexperience with Javascript:

view-source:http://econym.googlepages.com/example_geomulti.htm

I was wondering if someone could explain the following code in detail
to me with comments. There are several things I don't understand, such
as the multiple ===
also I cant see where he gives delay a value. I would greatly
appreciate some light on this code. Thank you very much

  delay// between geocode requests - at the time of writing, 100
miliseconds seems to work well var

    delay if =





    (GBrowserIsCompatible()) { Create





      // = a Client Geocoder var =

      geo GClientGeocoder(); = ===== Array



      // = for decoding the failure codes var =

      reasons reasons[G_GEO_SUCCESS]=Success

      ;            = ""reasons[G_GEO_MISSING_ADDRESS]

      ;    = ""reasons[G_GEO_UNKNOWN_ADDRESS]

      ;    = ""reasons[G_GEO_UNAVAILABLE_ADDRESS]

      ;= ""reasons[G_GEO_BAD_KEY]

      ;            = ""reasons[G_GEO_TOO_MANY_QUERIES]

      ;   = ""reasons[G_GEO_SERVER_ERROR]

      ;       = ""reasons[403]

      ;                      = "====="Geocoding



      // ====== function =

      getAddress(search, next) { geo.getLocations(search,

        function (result) {

          If

            // that was successful if

            (result.Status.code G_GEO_SUCCESS) = { Lets

              p var =

              document.getElementById("message").innerHTML += xml;
            }
            // ====== Decode the error status ======
            else {
              // === if we were sending the requests to fast, try this
one again and increase the delay
              if (result.Status.code == G_GEO_TOO_MANY_QUERIES) {
                nextAddress--;
                delay++;
              } else {
                var reason="Code "+result.Status.code;
                if (reasons[result.Status.code]) {
                  reason = reasons[result.Status.code]
                }
                var xml = '&nbsp;&nbsp;&lt;marker address="' + search

                document.getElementById("message").innerHTML += xml;
              }
            }
            next();
          }
        );
