If they are miscodings then not really, mostly because Perl allows you to choose subroutines/methods at runtime. So the interpreter can't know a pri ori what subs need to exist. If you need to check for a sub to see whether or not you should be calling it, for instance to see if an object has a particular method you can use the UNIVERSAL::can function, see perldoc UNIVERSAL for more info. Of couse having said all that, aren't you testing ;-) .... http://danconia.org -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
