I can't say that I agree with the advice to declare all of your our variables once at the top of your program. To my way of thinking this defeats the purpose of having the our function*. I have a once-per-function rule for our; if a function needs to use a global variable, then it has to request it. This means that when you come back to the code a year later, and are looking at just that one function, you can easily see that the variable is special (i.e. used by many functions). That said, the code you were referring to was definitely overusing our. It doesn't need to be attached to every reference to the variable. * yes, the variable is still visible to all packages in the same file without having to be fully qualified, but I consider that aspect of our a misfeature. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
