Still, the approaches from Randy and Roy certainly are accepted
Hi Randy,
The practice recommended for SeaDataNet is to specify a fill value for the flag
that is defined in the flag convention as 'missing value'. I always feel more
comfortable with explicit semantics.
Cheers, Roy.

Randy,
The oceanographic community uses a set of integer QC flags (0 to 9)
See document http://www.nodc.noaa.gov/GTSPP/document/qcmans/MG22rev1.pdf
and section 2 'Quality Flagging'.
One of the flags is for a 'missing value' = 9. Would that suit your fill value
case?
