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.
