John,
This is not exactly what you wanted, but get this working and then go from
there. I think you will have to look at http_url_get_raw (example9), but
Scott will point you in the right direction. See if you can compile this
program. Notice I "hardcoded" the URL encoding. This is needed in the simple
examples, but the encoder can be called directly when you get that far.
Then run it. It should display the file to the screen.

Greetings,
So I am trying to work with geo coding. Yes I will need to create a mashup
of all the local pizza places in RPG. Now this is some task.
My first step is to geo code all the places. I have found a www site that
will return the lat and lon for an address.
I downloaded the HTTPAPI and looked through the examples.
This is a very simple www service. I don't need to load a file, put data
into a physical or save information to the IFS. I just need to make the
call and get the data back in memory. I like the currency example. But am
at a loss as to how to convert it so that it would work for me. This also
might not even be the best example to use.
If your address was lets say the white house I would put in
http://rpc.geocoder.us/service/csv?address=1600 Pennsylvania Avenue NW,
Washington,DC
and the server would return to me 38.898748,-77.037684,1600 Pennsylvania Ave
NW,Washington,DC,20502 You could change the address to get your code.
So which would be the best example for me to work with so that I could make
the call and get back the coding?
As a side note....
I have tried to use the amazon example, but the link to get an account seems
to be broken. I have then found it and signed up. I put in my key and it
still failed.
This is my first venture into this crazy world. I know this might seem easy
to you, but I have to take a few baby steps first.
tia,
John
