The display contains the following fields:

After-image begin date — The date of the last AIMAGE BEGIN command.
After-image new date — The date of the last AIMAGE NEW command.
After-image open date — The date when the AI log was last opened.
After-image generation number — The generation number of the current AI extent.
Number of after-image extents — The number of AI files or extents.
Current after-image extent — The extent number of the current (busy) extent.
