Michael, The information is here on pages 127 to 128.
IBM states specifically that the callable interfaces can be invoked by COBOL. I have been using the authorized interface for zEDC for several years now, and I will be the first to admit that the documentation is obtuse and hard to follow with few examples, but it does work. Once you get it working, the technology is impressive. But not for the feint of heart.
