Hi Todd
The operation b = a[1,-1] is a slice operation where the first index is the start point and the second is the length of the array that you are retrieving - this is why you are getting nil for 'b' - the way to do this would be to use an inclusive range like this b = a[1..-1] - this will return the results that you expect.

puts "b.length = #{b.length}" ;Why is array b nil after the subarray? I expect it to be equal to "a"
minus the first element.Todd
