    Create returns DefSwitch;
    ---Purpose : creates a DefSwitch as Void

    SetVoid (me : in out)  is static;
    ---Purpose : sets DefSwitch to "Void" status (in file : Integer = 0)

    SetReference (me : in out)  is static;
    ---Purpose : sets DefSwitch to "Reference" Status (in file : Integer < 0)

    SetRank (me : in out; val : Integer)  is static;
    ---Purpose : sets DefSwitch to "Rank" with a Value (in file : Integer > 0)

    DefType (me) returns DefType  is static;
    ---Purpose : returns DefType status (Void,Reference,Rank)

    Value (me) returns Integer  is static;
    ---Purpose : returns Value as Integer (sensefull for a Rank)
