Warning Messages
A warning message alerts you to a possible problem and prompts you to respond before the system continues a task. For example, before you format a
diskette, a message will warn you that you may lose all data on the diskette. Warning messages usually interrupt the task and require you to respond by
typing y (yes) or n (no).
