# Can I do nicer than:

your code is already nice. it is readable to me. 
"nicer" is difficult to measure :)

if you do not like the ".." notation and 
if you do not like the to_s conversion,

you can eg do something like,

>cat test.rb

y=3
x=4

1.upto(y) do |i|
  1.upto(x) do |j|
    puts "rack#{i}#{j}"
  end
end

or

y.times do |i|
  x.times do |j|
    puts "rack#{i+1}#{j+1}"
  end
end


>ruby test.rb
rack11
rack12
rack13
rack14
rack21
rack22
rack23
rack24
rack31
rack32
rack33
rack34
