Let's Build a Compiler (1995)

With oberonc you can compile the source code at http://www-oldurls.inf.ethz.ch/personal/wirth/CompilerConstr... with minor changes to the I/O library calls. I can push the changes in a repo if you are interested.

Oberon-0 is too limited to easily bootstrap itself. I wrote oberonc first in Java and then I rewrote it in Oberon-07 for the final bootstrap step. Oberon-0 is a toy subset of the full Oberon-07 language.

Thanks. That would be great for the people that want to follow the Compiler Construction book. (Thanks for posting the link for the 2017 version)

    Oberon-0 is a toy subset of the full Oberon-07 language.

So I can write small Oberon-0 programs and try these using Oberon-07.

Here is the repo: https://github.com/lboasso/oberon0

Yes, you can write small Oberon-0 programs and compile them with an Oberon-07 compiler, but it is simpler to just use the Oberon-0 compiler from the repo above.

As a tip when using languages like Oberon, use an autoformatter that uppercases the keywords, no need for shift or caps turn on/off all the time.
