          DVMDOPM1 and DVMDOPM2 contain flags that indicate that
          the associated values in the DVMD were set explicitly
          rather than by default. They are only defined in cases
          where a default value is also a valid value that can be set
          explicitly and therefore it is not possible to determine
          whether the value was set explicitly or not without some
          other indicator. This distinction is important in HCPUDM
          when it merges IDENTITY and SUBCNFIG DVMDs during Logon
          processing. Values in a SUBCONFIG DVMD only override the
          values in the IDENTITY DVMD if they were explicitly set.
          These values are set in all DVMDs (SUBCONFIG, IDENTITY and
          USER) even though HCPUDM only requires them in SUBCONFIG
          DVMDs for merge processing.
