The FORTRAN "MF" interface provides a set of
routines for direct interface to the database structures in
the FORTRAN programming language. The routines are classified
into four groups:
- Open and close routines.
- Qualification building routines.
- Record retrieval routines based on qualifications.
- Record manipulation routines.

from within a FORTRAN program. The following operations on
tables in Empress databases are supported:
- Adding rows to a table.
- Updating rows in a table.
- Deleting rows from a table.
- Selecting rows from a table.
- Adding, updating and deleting all or part of a context
