so VARPG probably compiles the rpg code, captures the w-code, then
translates the W-Code back to C code and compiles it on the pc?

If so, is that all ibm proprietary?   Even if a developer pays the $$ for
the w-code compiler and documentation, does ibm still not provide a way to
capture the w-code that is output by its rpg and other compilers?
