Lock Result (\!) field switch
Prevents a field that is included in the result of a BOOKMARK, INCLUDETEXT, or REF field from being updated unless the field result in the original location has changed. Without this switch, Microsoft Word updates fields included in a field result whenever the BOOKMARK, INCLUDETEXT, or REF field is updated.
For example, the field { INCLUDETEXT C:\\Sales\Qtr4 Sales.doc \! } inserts the contents of the document "Qtr4 Sales.doc," which contains a DATE field and an EMBED field. If you update the INCLUDETEXT field, the "\!" switch prevents Word from updating the DATE and EMBED fields in the included text unless they are first updated in the original document ("Qtr4 Sales.doc"). The switch ensures that the text inserted by the INCLUDETEXT field matches the text in the original document. To update the DATE and EMBED fields in both locations, update fields in the original document ("Qtr4 Sales.doc"), and then update the INCLUDETEXT field.
