**OnChange( **//filename//**, **//file //**), VIRTUAL**

{{blk2blue.jpg|blk2blue.jpg}}

| **OnChange** | Initiates an update to the audit log file after a Change to the file. |
| //filename// | A string constant, variable, EQUATE, or expression containing the label of the file that is to be audited. |
| //file// | The label of the FILE being audited. |

The **OnChange **method initiates the update to the audit log file after a Change action.

**Implementation:**

The OnChange method is a VIRTUAL method so that other base class methods can directly call the OnChange virtual method in a derived class. This lets you easily implement your own custom version of this method.
