4th parameter inEnumOs -- you should almost never use. Practically never.

Docs should be corrected to use symbolic constants

Wait a moment, the number of db files is specified by 3d parameter.
All your examples have it 4. This is why you get 4 files always.

So if you want change mode of db, you need write

     get VDatabase_Create( dbRef, mPath, 1, 32 * 1024 )

Next, I am not sure that we it is good idea to allow numeric values of
constant at all !!!!!!!!!

In the next letter I will again describe how we going to make constants for
next build.
