in thread Atomic operations in perl and Tk::IO

because $_[0] is the same as $prch when you call tail_lines($prch, $_[0]), and this seems to be not what you want.
Sorry, hiseldl, you are not correct. The call to tail_lines is in an anonymous sub, which is a closure, which is passed a line of text by the Tk::IO mechanism.

See Tk::IO for more details

    I've been writing Tk scripts for over a year now, and I temporarily forgot about closures as callbacks, oops, sorry. I'll leave the post as it is to maintain continuity of the thread and as a reminder to other's using Tk to watch for closures in the callbacks. :-)

    Cheers!
