2.1.3 Global organization of the DBASE
The DBASE is a set of data and procedures which regulates the parameter manage-
ment of the DGF. For each parameter that has been put in the DBASE, an associated a
record of information which describes the parameter has been created:
-IPA parameter’s identifier.
-UNM 4-character label defining the measure unit of the parameter .
-DESCRIBE 10-character array which contains the parameter’s name.
-TYPE specifies the type of the parameter.
-PROCEDURE if this field is not 0, it is a procedure that will be carried out
each time the parameter is read or written.
-MINIMUM minimum value of the parameter.
-MAXIMUM maximum value of the parameter.
-LIMIT MINIMUM minimum limit of the attribute MINIMUM.
-LIMIT MAXIMUM maximum limit of the attribute MAXIMUM.
-STATUS OF ACCESS it specifies the modes of access for the reading and writing
of the parameter.
- LEVEL OF ACCESS it specifies the level of the password to enter into the parameter
modification.
-MEMO it specifies the storage modes of the parameter.
-DEFAULT parameter’s default value .
The collection of these records forms the DBASE area. For storage reasons, that will
be explained below, this area is multiplied 4 times.
- DBASE_RAM working area
- DBASE_ROM area in which the default records are stored
