We are about to celebrate silver jubilee of our RPG code, although I am with it since last one year. My question is, in one of our code file there is a call to a program with several parameters. In comments it is written "API call". Where I can find this API. I have tried a lot but couldn't find code file. Is it possible that there is only compiled version of this API. But I searched all objects also with no luck. Normally I find all called RPG or RPGLE programs within system but this API I couldn't find. Any idea?
