Baseline - you are certainly free to move to classes or any other concepts
you want to add on - but this would be a starting point

#!/usr/bin/ruby

def handle1
  puts 'Got 01'
end

def handle2
  puts 'Got 02'
end

def handleq
  @cont = 0
end

@cont = 1

while @cont == 1
  puts 'Pick an option'
  choice = gets.strip
  case choice
  when '1'
    handle1
  when '2'
    handle2
  when 'q'
    handleq
  end
end

P.S. Probably the trickiest thing in there for you is the gets.strip - ruby
will give you back the newline character when the person hits enter #strip
removes the last character from the string (newline character).
