Don't use prototypes. When you need them, you really need them. That's why they're there. But ( 1 - 1e-42 ) percent of the time you don't need them. Don't validate parameters for a sub. Assume the people using it are adults and are capable of acting in a responsible manner. Don't let them push their workload on you. The correct methodology is: 1. Get the input. 2. Validate the input. 3. Process the data. 4. Write the output. The only validation is the input data, not in each sub. -- Just my 0.00000002 million dollars worth, Shawn Linux is obsolete. -- Andrew Tanenbaum -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
