The SEQUENCE (abbreviated /SEQ) qualifier specifies the sequence of numbers to be assigned. The init parameter specifies the initial number, and incr specifies the number by which the lines are incremented. If you do not use the SEQUENCE qualifier, init and incr both default to 1. The maximum allowable line number is 2814749767. If, during resequencing, a line number plus 'incr' would exceed this value, that line and all remaining lines will be numbered 2814749767. You should correct this immediately by resequencing with a different 'init' and/or smaller 'incr'.
