NDF_SBB - Set a bad-bits mask value for the quality component of an NDF

Description:
The routine assigns a new unsigned byte bad-bits mask value to the quality component of an NDF.

Invocation:
CALL NDF_SBB( BADBIT, INDF, STATUS )

Arguments:
BADBIT = BYTE (Given)
The unsigned byte bad-bits mask value.
INDF = INTEGER (Given)
NDF identifier.
STATUS = INTEGER (Given and Returned)
The global status.

Notes:
  • If WRITE access to the NDF is not available, or if an NDF section is supplied (as opposed to a base NDF), then no permanent change to the data object will be made. In this case, the new bad-bits value will be associated with the NDF identifier and will subsequently be used by other NDF_ routines which access the NDF through this identifier. The new value will also be propagated to any new identifiers derived from it.
