The VSSWARN option provides a run-time indication of discrepancy between the blocking attributes of a structure and the storage device type upon which it resides. This option is specifically associated with VSS-2 devices. When the VSSWARN option is set to TRUE, the Accessroutines generates a durable warning message if the blocking attributes of the structure are not optimized for the members of the pack family. The message is sent as a task that is placed in the waiting mix. You can view the message by using the IB (Instruction Block) system command.

The VSSWARN option is most useful when a VSS-2 device is unexpectedly configured in a 180-byte aligned pack family.

The default is FALSE.
