  I'm stuck trying to do the part to make it do '99 bottles of beer on the
wall' song. I get started in what I hope will work and next thing I know I
have way too many variables and nothing makes sense. I even did something
that made it loop the integer 0. I had to Ctrl-c on that one. <sigh>

  Here's what I quit trying at, because no matter how many breaks I took or
whatever, it just wasn't making any sense. :


puts '99 bottles of beer on the wall, 99 bottles of beer,'
'take one down, pass it around,'
'98 bottles of beer on the wall!'
song = '99 bottles of beer on the wall, 99 bottles of beer,
take one down, pass it around,'
song = 99
song2 = '98 bottles of beer on the wall!'
song2 = 99 - 1
last = '1 bottle of beer on the wall'
last = 1

if song2 == last
        puts 'Yay!'
else
        if song2 - 1
        puts 
        while   song == 1
        end
endputs '99 bottles of beer on the wall, 99 bottles of beer,'
'take one down, pass it around,'
'98 bottles of beer on the wall!'
song = '99 bottles of beer on the wall, 99 bottles of beer,
take one down, pass it around,'
song = 99
song2 = '98 bottles of beer on the wall!'
song2 = 99 - 1
last = '1 bottle of beer on the wall'
last = 1
if song2 == last
        puts 'Yay!'
else
        if song2 - 1
        puts 
        while   song == 1
        end
end


  I too wish the author had put examples, say on some pages in the back or
something.
