Never mind the Unix programming environment, it's fine if you have even the slightest familiarity with perl. Shift is a keyword in the language. You might as well complain about a C program using 'void' or 'case'. As for readability, would you prefer this? my $string = $_[0]; @_ = @_[1 .. $#_]; cos that's how you avoid using shift. -- David Cantrell | Hero of the Information Age What is the difference between hearing aliens through the fillings in your teeth and hearing Jesus in your heart? _______________________________________________ get_iplayer mailing list get_iplayer@lists.infradead.org http://lists.infradead.org/mailman/listinfo/get_iplayer
