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).
