No, he doesn't. He isn't asking for multiple instances of counters. A single subroutine with an external variable (or an internal state variable) will do. `sub next_number {no warnings;++$::N} say next_number; say next_number; say next_number; __END__ 1 2 3` [download]	[reply] [d/l]

Note that my solution does not use any lexical variables.	[reply]
