Yes.

The FBII set of constants (listed in the on-line help and embedded 
for backward compatibility) are a requirement that we can't discard. 
However, if you create (or if we creat in the header files) a real 
record, then you know for a fact that use the same offset name in 
several different records and they will never be confused.
