The Objective-C compiler uses a recursive descent parser which reaches certain conclusions in the parsing process. The message you complain about says that BASED ON WHAT IT HAS SEEN SO FAR, the only legal token is a right paren. It has no way of knowing whether "toto" is wrong or something it has seen previously is wrong. We are coming out with a maintanence version of Objective-C version 4.3. It does not address the enhancement to the error diagnostics. Unfortunately, this is not a simple matter of changing error messages. The maintenance release is more directed on fixing ICpak101, C Preprocessor, objcc, and Objective-C known problems. The expected date of release will be in November/December of this year. It incorporates many bug fixes and enhancements that customers asked of us previously. In regards to the error messages, we have made minor improvements in this area also. The documentation will be a new reprint and has reported errors corrected in it along with a better description of static binding and optimizing Objective-C code. -- The Stepstone Corporation Michael Goda 75 Glen Rd. mikeg@stepstone.com Sandy Hook, CT 06482 uunet!stpstn!mikeg (203) 426-1875 fax (203)270-0106
