Thank for your help, I could read it in fixed m , but i am researching how could I know max of m value because I need to take values from the last two nodes(c57 & c62)?

m is changed from record to record, sometimes m=3, value of m I need to read is m=3 for first record and m=2 for second record. When m=2, it should be m=2 for first record and m=1 for second record

Thank
