About Your System 35
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 the documentation that accompanied the operating system or application.
