Dear Jim,
I followed your recommendations, avoided the "I don't want delimiters in my
language" temptation, and created the grammar from scratch using ANTLRWorks
successfully.
Next steps for me: AST + StringTemplate output.
Thanks a lot for your answer. It was exactly what I needed.
Sincerely,
Arye.
Remove your tokens section and place those keywords as real lexer rules that
