The RPG compiler is a single-pass compiler

No, it can't be pure single-pass. If it were, then a program in which a variable is NOT defined in a D-spec, nor in the first C-spec in which it appears, would not compile, much less run. And it's trivially simple to construct an example of this (it took me about 2 minutes), and it compiles and runs just fine. I'd quote the source here, but it would likely be mangled beyond recognition.
