I have a grammar file Bookings.g and the file I try to parse with that grammar.
Why am I getting these errors?
line 1:12 extraneous input '"pcc"' expecting String line 3:0 mismatched input '}' expecting ScenarioPart1 line 7:13 mismatched input '"R"' expecting String line 9:8 mismatched input '"Doll"' expecting String line 15:8 mismatched input '"Train"' expecting String line 21:8 mismatched input '"Ball"' expecting String line 34:0 missing EOF at '}'
