The Editor allows you:

To remove a record,
To rebuild an index,
To modify the automatic sequence number of a file,
To reset the flag to zero, depending upon the result of the last change made to the database.

This last button is only active if the last operation carried out in the database goes badly. The following are examples of bad operations:
- Interruption when backing up the bit file,
- Interruption when backing up the index,
- Interruption during the removal of an index,
- Invalid record address,
- Interruption when flushing the cache.

To Rebuild the Indices

To rebuild an index, click on the Rebuild Index button.

The following window appears:

Select the table and the field which you want to rebuild.
The substructures are not represented. Because of how substructures function, recreating the index of one substructure in the file is a delicate operation. Hence, if you want to rebuild the index of a substructure, Rescue For 4D Data will rebuild all the indices in the substructure (and the included substructures).

Validate by clicking on the icon. A confirmation dialog appears:

To cancel the operation, click on the No button.
To rebuild the index, click on the Yes button.

To modify the Automatic Sequence Number

The following window appears:

Select the table in which you want to modify the automatic number.
The automatic sequence number dialog appears:

Modify and validate it by clicking on the icon. A confirmation dialog appears:

To cancel the operation, click on the No button.
To modify the sequence number, click on the Yes button :

If everything went well, Rescue For 4D Data will display a confirmation dialog:
