It sounds like you completely missed the point of Crenshaw's tutorials. LBC isn't about writing pretty, clean, or efficient code. It's all about bringing something that's steeped in formal theory down to a level where the casual coder can easily and rapidly hack out a rudimentary (but working!) compiler.
When I read through LBC years back, I rewrote the examples in C#. I'm sure the class layout isn't the best, or tasks segregated properly, but it's comparable to his Pascal. I'd be happy to share the code with you if you like-- let me know and I can post it online and share the link.
In my spare time I've been hacking out some writing with the aim of unifying the philosophies of LBC and Basics of Compiler Design together-- walkling away with practical, working code at the end of each unit/chapter, with also discuss some theoretical stuff after exploring the ideas so the reader understands why things are the way they are. But it took Crenshaw years to write his incomplete series, so mine my be a pipe dream... and I use C (exactly because it's not C++ or Java).
