Your understanding is correct. Concatenation works on scalars, so the array is evaluated in scalar context, returning 3, which is concatenated with "\n" and then printed. In the second line, print takes a list, so the array is evaluated in list context. -- Paul Johnson - [EMAIL PROTECTED] http://www.pjcj.net -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
