Okay, now I better see what you want.

    Function instead of numeric value?
    Function which return CURRENT format which plugin do use ?

if Valentina.GetDatabaseVersion((theFile) < &h200 then
 ...
Else
  Msgbox "This is a v1 file."
End if

Can you show code of task which you cannot solve now ?

    currentFormatVersion = new function you want()

    foundFormatVersion = Valentina.GetDatabaseVersion((theFile)

    if currentFormatVersion = foundFormatVersion

    else

    end 

?
