UNESCO ICTLIP Module 4. Lesson 5
Note
The backup option of the DOS version is not available in the Windows
version. Instead EXPORT/IMPORT functions are available.
During EXPORT/IMPORT functions, a Field selection table (FST) can
be used to limit the parts of a record to be exported/imported or to
move data from one field to another. This means a database can be
reformatted by exporting and re-importing it.
The record structure used for importing and exporting is known as
ISO 2709, which allows the import or export of MARC records.
