Subject: re-opening STDIN after it's been closed?

Content-Type: text/plain; charset=ISO-8859-1

here's a summary of a script I just wrote:

while (true) do
puts "Make your selection from the list below: \n\n"
puts "a) foo\n"
puts "b) bar\n\n"
gets
handle_action($_)
end

handle_action does stuff that isn't relevant to my question.

The program works fine except when I hit CTRL-D. After I hit CTRL-D, the=20
program runs in an endless loop and seems to skip over the gets statement.=
=20
Doesn't look good, I can't even break out of it (CTRL-C). Of course CTRL-D=
=20
indicates end of file. My guess is that this closes STDIN.

I just thought of a "work around", consisting of inserting

exit unless $_

after the gets statement

I think it might be better to simply re-open STDIN as if nothing had=20
happened.. is this a good idea and is it possible?

Thanks,
