SEQUENCE name start increment frequency maximum
Instructs Post to precede each line of output with a sequence number. It will use Block Template name to control the format of the output sequence number (see the description of Block Templates below). The numbers printed will be the sequence start, start + increment, start + 2*increment, start + 3*increment, ..., start + i * increment. The sequence block will only be output on lines that are a multiple of frequency. For example, if frequency is 3 then only lines 3, 6, 9, ..., will be preceded by sequence blocks (assuming the addresses in the sequence block are not suppressed, see this section for a discussion of suppress). When the sequence number exceeds this maximum value the event generator will invoke the event name sequence_overflow in the event handler if the procedure MOM_sequence_overflow is present. If the procedure is not present then the even generator resets the sequence number to start. The variable mom_seqnum is the event generator variable that is assumed to store the sequence number.
