I've got a file INPUT that has the following contents:

123\n
456\n
789

I want to run my script like so: script.rb < INPUT and have it convert the contents of the INPUT file to an array, splitting on the new line character. So, I'd having something like myArray = [123,456,789]. Here's what I've tried to do and am not having much luck:

myArray = STDIN.to_s
myArray.split(/\n/)
puts field.size

I'm expecting this to print 3, but I'm getting 15. I'm really confused here. Any pointers?
