Re: will v6r1 RPG support main procedure recursion?

Now, in order to make OO virtual machines work outside their sandbox, there
are GC issues, which is why most folks don't do it. At the most, they might
let Java call their native non-Java functions (through JNI), but rarely vice
versa. In a rather stunning architectural achievement unlike any other
operating system that I'm aware of, the i5/OS interface between RPG and Java
has support to directly invoke Java methods, and thus there is a need to
directly invoke the GC functions -- which IBM has provided and which Barbara
has kindly shown in specific detail in other posts.

Joe, the calling from RPG to Java also uses JNI. Without JNI, I think it would have been impossible for RPG to call Java methods. It's possible to use JNI to call to/from Java on every platform that supports Java. (Although it may involve nastier coding than RPG does.)
