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).
NOTE: Warning messages are generated by either the application or the operating system. For more
information, see "Finding Software Solutions" and the documentation that accompanied the operating
system or application.
