``` pascal program llvm; var a, b, c: integer; a, b, c: integer; ... ``` Codes like this will pass the check, `a,b,c` should not be allowed to declared again....
1. const_value (real, char, boolean) 2. array_type_decl 3. record_type_decl
Two sets of error: 1. compile error 2. running error More subtypes in each set. E.g. syntax error and invalid type error are both compile errors
