Consume Web service

Hello guys

Ran into an old article by Mike Faust dealing with consuming a Currency
converter
Web service
http://www.mcpressonline.com/rpg/cool-things-ile-rpg
-as-a-web-services-client.html
I followed the article and created the A/M utility
(with some difficulty- had to re-installed the C compiler)

I does run but it returns a value of -1 which I assume indicates some error.
For some reason or other I'm not able to debug the C part of it , only the
RPG part
(I admit to being close to a complete C ignorant anyway)

Is anybody familiar with this Web service? I surly could use some pointers.

Alternately, could you point me to another Currency conversion Web server?
