How to decode ASSN_CHANGE_DATA and TASK_CHANGE_DATA

[kernel]

All,
I am trying to decode the below PSI change field data. I would like to
translate the change data into something human readable.


StatusApprovalDataSet.StatusApprovalsRow.ASSN_CHANGE_DATA and
StatusApprovalDataSet.StatusApprovalsRow.TASK_CHANGE_DATA

Thanks!
