So it is a parser then, that IBM have decided to call a reader?

Uh, the technical term for the "lexical" stage, that recognizes tokens
in an input stream, and passes them to a parser, is "scanner."

The lexical stage is the scanner.

The syntactic stage, which is usually in overall control, is the parser.

The semantic stage is either a code generator, or a direct executive.

That is about as fundamental as compiler theory gets.

And BTW, I can tell you from experience that it is entirely possible to
write a recursive descent parser in ILE RPG. I've done at least two myself.
