Only because I'm writing for beginners, and (I hope) an &-sigil on a subroutine signals even to a beginner that we're calling a user-written subroutine and not a built-in function. (That might seem more important if the sub had a different name than the example above.) My programming style in this forum (or in the classroom) is somewhat different than the way I actually write Perl code in the real world: Here, I usually spell out foreach to distinguish that from the three-part for loop, even though doing so makes no difference in Perl. But when I write my own code, I type F-O-R just like everybody else. :-) Cheers! --Tom Phoenix Stonehenge Perl Training -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
