I just had a similar problem: "how do you determine your entry R0 from C?" I asked here and got no answer. I had to front end the C with a tiny assembler program (57 lines including extensive comments; 11 executable instructions). Why did the C need its entry R0? Because it is called from Rexx, and needs to call IRXEXCOM, and so needs the Rexx environment block.
Why the ^%$^%$#$^% do people come up with these non-standard linkages? Rexx passes a bunch of parameters -- why not pass the Environment Block address that way?
