If I wanted to write to a particular NestedStructure in BigRecord, from exampleDatabase.cpp,
what would be my syntax?  I cannot find this documented.

I have:
  PVRecordPtr pvPtr = PVDatabase::getMaster()->findRecord("myRecord");
and I'm expecting to need to do something like:
  PVDoublePtr pvReading = pvPtr->getPVStructure()->getNested???()->getSubField<PVDouble>("value");

What should I have instead of getNested?

try

PVDoublePtr pvReading = pvPtr->getPVStructure()->getSubField<PVDouble>("scalarArray.double.value");

Marty
Thank you,
