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