Warning Messages A warning message alerts you to a possible problem and asks you to do something before execution continues. For example, before you format a floppy, a message may warn you that you may lose all data on the floppy as a way to protect against inadvertently erasing or writing over the data. These warning messages usually interrupt the procedure and require you to respond by typing y (yes) or n (no). 202 Solving Problems
