Apparently if you are running ActivePerl on Win98 there is a known issue with CTRL-Z. The first run of the script is reported to run fine although I am unsure if that is always true. Thereafter, at least for that session, all input up to the first newline is lost. There may be workarounds for this, but as I am only doing Llama tutes right now I have chosen to ignore it and focus on learning the lessons.
