Looks crummy w/o whitespace, but this was as short as I could get it :)
puts (1..10).map{|i|"#{i} squared = #{i**2}"}<<"Program Complete."

I never thought about using the map method. Thanks. =D
My re-factored code:
#!/usr/bin/env ruby
puts (1..10).map{ |i|"#{i} squared = #{i**2}" }, 'Program Completed.'
=begin
Outputs:
1 squared = 1
2 squared = 4
3 squared = 9
4 squared = 16
5 squared = 25
6 squared = 36
7 squared = 49
8 squared = 64
9 squared = 81
10 squared = 100
Program Completed
=end
I looked at the code examples at http://en.wikipedia.org/wiki/Spaghetti_code, and thought I could write a program which produces the same results in Ruby. However, being new to the language I am not sure if this program can be made more compact and concise. What do you guys think?
