Tracking value

For DFSMS instances, the EAV migration assistance tracker sets the tracking value as follows:

The system sets the low order byte of the track value to the same numeric value that identifies the reason for the instance.
The remaining high order 3-bytes are left for the function recording the tracked instance. These 3-bytes are optional. For example, these values could be set to return and reason codes or parameter list flags.

Note that the tracking value must be set to a non-zero value in order for the SETCON TRACKING=ONWITHABEND to be applicable when an instance is recorded in the tracker. If the track value is 0 or 128 no ABEND will be issued when you specify tracking ONWITHABEND.
