| NAME |
F |
| DESCRIPTION |
The F index, is a whole file compound cross-reference on two fields in the
Cross-Reference Values multiple: File (#2) and Field (#3). It lets FileMan
identify the indexes that might be affected when a field value changes.
The checking of this index is an essential step during field level
transactions in building the list of record level cross-references that
must be fired after user-driven changes to the record are finished.
