Let's try this again.  I understand what Valentina.GetDatabaseVersion 
does; it tells me the file format version of the file.  V4Rb expects to 
see a certain database file format.  How am I to know what that format 
is, so that I can compare that to the value returned by 
Valentina.GetDatabaseVersion?

In other words, given the code

If Valentina.GetDatabaseVersion((theFile) < &h200 then

I want to replace the &h200 on the right-hand side with a Valentina 
module function that returns the file format version expected by V4Rb.
