Subject: Re: Adding user input to a hash

Thanks for that reply. I think that I will go for the two array
method. One for the input and the other to save the data. On a
side-note but related issue I'd like to save this data to a file. The
name of the filename to be created is based on the user input....

jayeola@tp20$ cat testwrite_using_filename.rb
#!/usr/bin/ruby -wv
def testwrite_using_array
  ask_list = [ 
              'Your name', 
              'Your stuff', 
              'Your foo', 
            ]
  array_counter = 0
  user_response = []
  ask_list.each {
    |z| puts "#{z} : "
    xx = gets.chomp
    if xx.chomp! != "qq"
      array_counter += 1
      user_response += "#{xx}".to_a  
      # puts array_counter # check number of elements in array
    end 

  }
    puts user_response
    # name of next variable used user respose....we need to save this
data to a file name like "name + age + foo".txt 
filename =user_response[1..3].to_s 
puts "filename #{filename}.txt created"
    File.open(filename, "a") { "#{user_response}" } 
end

testwrite_using_array


# So far the file is created, but nothing's in it - it's empty...I know
I'll get there. Just need a few pointers. Any ideas chaps?
