Hello,

You are right - I get nan for the lo/hi warn/alarm fields using caget. 
It doesn't matter if I use the quotes or not. The IOC doesn't display 
any errors when loading this db.

Does the fact that the native data type is DBF_DOUBLE have anything to 
do with it? I wonder why only those four fields are invalid in this case.
