Sub-ranges feel like quite an obscure feature of a language. But in Pascal they're an essential part of arrays
array ['a'..'z'] of Integer
So I'm filling out their implementation before I continue with arrays. The next step is the assignment validation when range checking is on.

Before I got sidetracked into the type system I was working to get the command line compiler fully up and running.

The sticking point was command line arguments. I tried using #FreePascal's built in parser but it didn't have the flexibility I needed. I've now written something which does and I can now set the platform and deployment options.
