Subject: Re: How to read a single character from DOS prompt in windows (without <Enter>)?

Hmmmm.  This worked ok in my little test file, but the character is
still in a buffer somewhere.  In my program, I hit 'n' to not do
something, then 'puts' to the command line with no problem -- then
when I do a 'gets' the 'n' prints out.  What the heck?

require 'Win32API'

print "Question? (Y/N): "
char = Win32API.new('crtdll', "_getch", [], 'L').Call
putc char
putc ?\n
if [?y,?Y].include? char
	puts "You pressed 'Y'"
else
	puts "You pressed something other than 'Y'"
end
gets	# this prints the 'y' or 'n' !!!
