]> I wrote a parser originally in ocaml 3.02 and it works well. It was a suprise for me to receive an error message when I tryed to compile it in ocaml 3.07. The error message I receive is: File "selexerlse.ml", line 21, characters 6-8: Syntax error File "selexerls.ml", line 27, characters 6-8: Syntax error File "selexersus.ml", line 74, characters 6-8: Syntax error File "subsexpl.ml", line 129, characters 45-47: Warning: Illegal backslash escape in string make: ** [depend] Erro 2 The error occurs exactly at the same string in three files (selexerlse.ml, selexerls.ml and selexersus.ml) above. It in the first occurrence of [< in the code below: let rec parse_expr1 = parser [< 'Ident s >] -> (Vr s) | [< 'Int 1 >] -> (One) | [< 'Int n >] -> (convertN(n)) | [< 'Kwd "A"; 'Kwd "("; e1 = parse_expr1; 'Kwd ","; e2 = parse_expr1; 'Kwd ")" >] -> A(e1,e2) | [< 'Kwd "L"; 'Kwd "("; e1 = parse_expr1; 'Kwd ")" >] -> L(e1) | [< 'Kwd "Sb"; 'Kwd "("; e1 = parse_expr1 ; 'Kwd ","; sb = parse_subs; 'Kwd ")" >] -> Sb(e1,sb) and parse_subs = parser [< 'Kwd "Id" >] -> (Id) | [< 'Kwd "Up" >] -> (Up) | [< 'Kwd "Pt"; 'Kwd "("; e1 = parse_expr1 ; 'Kwd ","; sb = parse_subs; 'Kwd ")" >] -> Pt(e1,sb) | [< 'Kwd "Cp"; 'Kwd "("; s1 = parse_subs ; 'Kwd ","; s2 = parse_subs ; 'Kwd ")" >] -> Cp(s1,s2) ;; Does anyone know what is the problem?
