```How's this for a solution.  Note I tried to only use constructs covered
up to the point of the exercise in the book.

numBottles = 99
while numBottles > 2
puts numBottles.to_s + " bottles of beer on the wall, " +
numBottles.to_s + " bottles of beer,"
puts "take one down, pass it around, " + (numBottles-1).to_s + "
bottles of beer on the wall!"
puts ""
numBottles = numBottles - 1
end
puts numBottles.to_s + " bottles of beer on the wall, " +
numBottles.to_s + " bottles of beer,"
puts "take one down, pass it around, " + (numBottles-1).to_s + " bottle
of beer on the wall!"
puts "Yay!"

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.
