Janek gave you the difference, and it's fully documented in perldoc perlsub. Note that the first is not allowed under "use strict" unless the sub has been declared or defined above the usage, or imported. Here are my recommendations for new code (others may want to debate these): 1. Always "use strict;" 2. Don't use prototypes. 3. Don't use the &foo or &foo(args) calling styles. 4. To call a sub with no arguments, use an empty set of parens: foo() (Exception: method calls can leave off the parens, e.g: $sth->execute; since there is no ambiguity with a method call). -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
