I don't know why this is so hard for me to get my head around, but 
thing's just aren't working out as I'd planned. Martin, I've followed 
your iterative approach, but I can't seem to implement each specificity 
into a conglomerate program. I have discovered #ruby-lang & I use it 
quite frequently, but it's much more difficult to explain the problems 
I'm having when I need to explain, in detail, what it is I'm doing, what 
I've tried, etc. In large part, that difficulty pushed me to posting 
here. Now, because you've said you're busy with work & unable to fiddle 
with any real-time stuff, I'll continue to post my questions here. As 
for the iterative approach & what I've written for each:

0.

puts
puts "Please say something."
puts
reply = gets.chomp
puts
puts "You said #{reply}."

1.

loop {puts "Please say something."
puts
reply = gets.chomp
puts}

2.

puts
puts "The world is flat. True or false?"
puts
reply = gets.chomp.downcase
 if reply == "true"
   puts
   puts "You must've read Thomas L. Friedman's book!"
 elsif reply == "false"
     puts
     puts "Ah, submitting to Pythagoras' proposal that"
     puts "the world is round, I see.  That's so 2,508"
     puts "years ago!"
end

3. (I cannot take ownership for writing this. sepp2k from #ruby-lang 
helped me considerably. He alerted me to the fact I shouldn't be using 
go-to style flow control & told me looping was the better bet.)

reply = "abc"
while reply != reply.upcase
  puts
  puts "Simon says, 'Input your text in all"
  puts "caps!  Otherwise, I won't echo back"
  puts "anything you say!   Instead, I will"
  puts "spit out my 'Simon says' spiel once"
  puts "more. & you wouldn't want that!"
  puts
  reply = gets.chomp
end

puts reply

... for now, that's all I've got. I've been working on each individual 
step of the iterative approach & trying to pick up what I can through my 
questions on #ruby-lang. I'll post the code for 4 & 5 later on in the 
day. Please take a look over what I've written (with the help of an 
array of people) & let me know if there's anywhere I can clean it up. 
Thanks!
