As mentioned in the title, the customer wants to perform recovery using only the vabs dat file without prevabs. However, to my knowledge, starting with vabs 4.0, the recovery flag in the dat file has changed to a damping flag, so it cannot be executed using the same method as in vabs 3.0. Could you possibly tell me how to perform recovery using a dat file in vabs 4.0 or 4.1?
Please read VABS 4.1 manual section 6.
