Here is the definitive explanation: http://www.cs.utexas.edu/users/EWD/ ewd02xx/EWD215.PDF . I have never, ever, seen a situation where the use of goto would have resulted in clearer code. Considering it has always indicated to me that the person considering it has not understood the problem properly or modeled its solution well. Goto simply is not part of the vocabulary of clear coding. -- Peter Scott http://www.perlmedic.com/ http://www.perldebugged.com/ http://www.informit.com/store/product.aspx?isbn=0137001274 http://www.oreillyschool.com/courses/perl3/ -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
