title: How do I display another prompt when the user hits the "enter" key?
body: <p>I'm writing a program to eventually translate words into pig latin and so far, I've stored the characters of the user input into separate memory locations (words can be 19 characters max). </p>
  
  <p>Now I want to print another prompt when the user hits the enter key (after they're done typing their word in english). I've looked at some examples and I see that they have a line near the bottom of the program that says "NEWLINE .FILL x00A". I understand that this is the ASCII code for the enter key, but I'm not sure how to tell my program that another prompt needs to be displayed after hitting "Enter". Any tips or ideas are appreciated!</p>
