Re: Anyway to produce the assembly or C language from a compiled RPG program?

MI programming you can code by hand. There was a guide out there,

https://svalgaard.leif.org/as400/

But it's not finished.

W-Code is generated by the ILE compiler, and as far as I know there is no way to hand code this. Or, for that matter, even see it.

This would pre-suppose that RPG (or indeed any language on IBM i) compiles
down to C. They don't. All ILE compilers output a variant of IBM's w-code

In the case of OPM compilers, they produced MI as the intermediate language.


Jon, can you explain a bit about the difference between MI and W-Code (or
point to some such discussion)? Thanks.
