2.1.5 FVAR, IVAR and NUM
The DBASE and the FVAR and IVAR arrays have been described in the previous
paragraphs. We can imagine the DBASE as a data array that has been assembled in
connection with its function and destination.

The observation of this table allows us to note that data written into retentive and
volatile groups will be lost at DGF power off.
2.1.6 DPRAM organization
The drive and the DGF are two devices that can be configured or conditioned through
the parameters. There are two different set of parameters: one for the Drive and one for
the DGF. The DGF can condition the Drive’s working by acting on its parameters.
Reading and writing from the DGF to the parameters of the Drive occurs through the
DPRAM.
