UPDATE If the SEQUENCE control statement is processed after updates have been
applied, no warning message is issued.
Each source record is resequenced in columns 73-80 as it is written
onto the output file, including unchanged records from the source file
and records inserted from the update file. -- inserts all

is a one-to eight-digit numeric field specifying the
decimal increment for sequencing the inserted records.
All records following the "./ I" statement, up to the next control
statement, are inserted in the output file following the record
identified by the "seqno" field. If the NOINC option is specified, each
inserted record is identified with asterisks (********) in columns 73-80. If either the INC or CTL option is specified, the records are
inserted unchanged in the output file, or they are sequenced according
to the "seqstrt" and "seqincr" fields, if the dollar sign ($) key is
specified.
The lefault sequence increment, if the dollar sign is included, is
determined by using one tenth of the least significant, nonzero digit in
the seqno field, with a maximum of 100. The default seqstrt is computed
as segno plus the default seqincr. For example, the control statement:
./ I 2600 $ 2610 causes the inserted records to be sequenced XXX02610, XXX02620, and so
forth (NOSEQ8 assumed here). For the control statement:
./ I 240000 $
the defaulted seqincr is the maximum, 100, number is 240100. SEQ8 is assumed, so
sequenced 00240100, 00240200, and so forth.

If either INC or CTL is specified but the dollar sign is not
included, whatever sequence number appears on the inserted records in
the update file is included in the output file. 204 IBM VM/370 CMS Command and Macro Reference

All records of the input file, beginning at seqnol, up to and

is a one-to eight-digit numeric field specifying the
decimal increment for sequencing the substituted
records. All records of the input file, beginning with the seqno1 record, up
to and including the seqno2 record, are replaced in the output file by
the records following the ".1 pll statement in the update file, up to the
next control statement. As with the ".1 D" (delete) function, if the
segno2 field is omitted, only a single record is replaced, but it may be
replaced by more than a single inserted record. The "./ R" (replace)
function is performed as a delete followed by an insert: thus, the
number of statements inserted need not match the number deleted. The
dollar sign ($), segstrt, and seqincr processing is identical to that
for the insert function.
