puts "Enter field length"
max = gets # vars starting with capital letters are constants
           # plus, you want to input Max, not Field in your C++ code
	   # anyway

field = [] # or field = Array.new
0.upto(max) {|i|
  print "Insert #{i}. Number: " # puts adds a newline; print does not
  field[i] = gets # arrays can be grown dynamically 
}
