Subject: Workaround for "conflict" between ARGV and gets?

gets looks to ARGV, if populated, for its source of data.  That is its
documented behavior.

I want to:
1)  use ARGV to point to a directory I want to process and
2)  use gets to inquire whether the user wants the program to proceed
with that directory.

I thought I might be able to reset ARGV to an empty array after I
saved its content, but that doesn't work.  Is there a way around this.

The following code never pauses to allow the user to enter yes/no, as
I intended it to.  Is there a workaround?

=== Code ==
puts "ARGV = %s" % ARGV.join(", ")
argv = ARGV[0]			# Save ARGV's content
ARGV = []				# Reset ARGV to an empty array
puts "Delete indicated item [yes, no]"
STDOUT.flush
response = gets.chomp	# doesn't go to STDIN !!!
puts case response
  when /^yes$/i; "Deleting"
  when /^no$/i; "Quiting"
  else; "Huh?"
  end
puts "EOJ"

puts "EOJ"
