I read in an earlier post that someone had created an ANTLR file for BASIC or C.
Do you still have the file? I am new to ANTLR but would like to create a parser for users entering at least BASIC code.
Thanks!

There is an Antlr grammar file in
https://sourceforge.net/projects/maverick/
At maverick-0.3.zip\\maverick-0.3\\src\\org\\maverickdbms\\tools\\BASIC.g.
It's hard to understand (I don't know antlr) but it looks like a good start, even if it's from 2006...

I think maybe AbstractTreeWalker.g (in the same "tools" subdirectory) may be a little easier to understand if you are just looking for a BNF. This is a more primitive abstraction of the BNF without the specifics of Java embedded within. It's still kind of confusing, unless you have at least a basic understanding of how grammars are written. When we were working on this all those years ago. I remember many hours of head scratching. Robert Colquhoun was the brains behind the operation, I was just a pack mule.
