Subject: Ruby TUI

I'm creating a program with a TUI to then later implement a GUI using TK
but for now I'm having trouble coming up with a menu system that works 
without a whole lot of loops and calls, which is what I have now but its 
starting to get really messy and confusing, any suggestions. Somthing 
along the lines of this:

Root Menu
  |-Option1
  |  |-subOption1
  |  |-subOption2
  |
  |-Option2
  |-Exit

main_menu.call #gets and returns menu_option
  case menu_option
    when '1'
    list_pos.call
    main_menu.call
    when '2'
      lookup_menu.call
      case menu_option
        when '1' then list_pos.call
        when 'B' then main_menu.call
        else $aMenu.error
      end
...
end
