Reply.Adding fields. You can add fields to your table using ArcCatalog or ArcMap. In ArcCatalog, you need to open the layer or table's Properties dialog box and add the field to the list on the Fields tab. In ArcMap, you can add a field through the attribute table of a layer or through the Catalog window by accessing the same Properties dialog box and Fields tab. Inside either application you can ...code sample. You want to split the text that the field contains, therefore, you write the name of the. field (enclosed in exclamation points), and on that you do the split method.
