#original program: r1test.rb

puts "Enter 32 or 64 bit:"
STDOUT.flush
answer1 = gets.strip.chomp

puts "Enter the path where you wish to install:"
STDOUT.flush
answer2 = gets.strip.chomp

puts "Your answers were:"
puts answer1
puts answer2
STDOUT.flush

----------

#driver program: r2test.rb

pipe = IO.popen("ruby r1test.rb", "w+")

f = File.open("answers.txt")

pipe.gets  #Enter 32 or 64 bit:
pipe.puts(f.gets.chomp)

pipe.gets #Enter the path:
pipe.puts(f.gets.chomp)

puts pipe.gets, pipe.gets, pipe.gets

puts
puts "Hit enter to end program"
gets

----------------

$ ruby r2test.rb
Your answers were:
32
./test_programs

Hit enter to end program
