In article <35384@brunix.UUCP> drc@cs.brown.edu (David R. Chase) writes: [well a bunch of stuff deleted, you'll have to read them yourself] Both Dan and David make good points. One alternative that hasn't been mentioned yet is implementing a module for exception handling. Such a module requires a bit of assembly language coding for the implementation but it can (and has) been done. This is how MacApp(R) implements a signaling exception mechanism in a language without exception handling features (Object Pascal). This overhead at run-time is minimal. So you can have an efficient, exception mechanism in a language without exceptions. BTW, the Metrowerks Modula-2 compiler for the Macintosh(TM) provides just such a module. -- Chuck Lins | "Exit left to funway."
