ArcView ArcMap does not have coverage editing capabilities. Refer to the "What is ArcGIS" booklet for more information.
If you attempt to edit coverages in the ArcView version of ArcMap you will receive the message:
"Could not edit the data in the folder or database you selected. Check to see that you have the appropriate permissions."
The ability to edit coverages comes with the the ArcEditor and ArcInfo versions of ArcGIS.
