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