Can someone tell me the behaviour of next_in_sequence() and innovation_number() in a multifile. Suppose I have records 1,1,1,2,2,3,4,4 in a 4ways mfs file. Data in each partition is: 0th : 1,1,1 1st : 2,2 3rd : 3 4th : 4,4 What will be the sequence of these records if I pass next_in_sequence() and innovation_number() ? Also how can I extract 3rd record from each of the 4 partitions of a 4way multifile through AbInitio? In unix we can use m_dump
