Action W? is used in the report design facility only.
When action W? is used:
A message is displayed on line 24 indicating what columns of the report image are being viewed via the current "window".
Some points about "windowing" are as follows:

• The "window" over the report image is required because very often report image dimensions exceed the dimensions of a workstation screen in both width and length.
• The workstation screen is considered to be a "window" through which the full report image can be viewed. Since the report image is larger than the workstation "window" it is necessary to move the "window" around to view various parts of the report image.
• W? is the action used to inquire about what columns of the report image are being displayed in the current screen window.
