The ArcMap Field Calculator lets you perform simple as well as advanced calculations on all or selected. The calculator knows to run it on the Comparison field because that's where I started it from. In the Comparison = box I can invoke (great word there) the function and tell it to use specific fields as the input variables. To demonstrate this I'll use the Name_2001 and Name_2008 fields. The image below pulls all this together and should do the trick
In ArcGIS, the field calculator in ArcMap can be used to set values for a single field in a single record, a field in a subset of all records, or a field in all records in a table.
