Addressing just the loop/goto issue, how about summat like:
#!/usr/bin/env ruby
done=false
until done
puts ' '
puts ' '
puts '****************************'
puts '** (Rules of the program) **'
puts '****************************'
puts ' '
puts 'Ohh, hello there! What are you named many names?'
names = gets.chomp
if names == '2'
puts ' '
puts 'Are you named two names?'
puts ' '
answer = gets.chomp
done = true if answer == 'yes'
end
end
#This is where "the program continues"
puts 'the end'
This gives me the output:
lnx:scratch : blah.rb
****************************
** (Rules of the program) **
****************************
Ohh, hello there! What are you named many names?
2
Are you named two names?
no
****************************
** (Rules of the program) **
****************************
Ohh, hello there! What are you named many names?
2
Are you named two names?
yes
the end
cheers,
