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

[VERNON HAMBERG Owner <vhamberg@xxxxxxxxxxxxxxx>]

Jack, since I've been known to play with MI instructions some in RPG, I'll take a shot, too - Jon says it here, I think, W-code "...is then translated down to machine instructions..." - "machine instructions" is MI, the actual instructions, so far as I can surmise.

Cheers
Vern

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