The simplest program in standard Pascal is not runnable:

program Hello;
begin
    writeln('Hello, World!');
end.

$ java -cp build/:Trupple.jar cz.cuni.mff.d3s.trupple.compiler.CompilerMain Hello.pas
-- line 1 col 1: invalid Pascal
Errors while parsing source file, the code cannot be interpreted...

The grammar file is missing "program" identifier on the "right side" of Pascal rule
