Hi,
I have the following request:
I have an array of NAMEs (about 70-80 different NAMEs), each NAME can be represented an unknown number of times. I need to add a sequence number to each row containing the same NAME, but the seqnum must only be incremented each 5th row. When a new NAME is encountered, the seqnum must be reset. The output should be a single file with the NAME and the seqnum. Example:
| Code: |
NAME1 1
NAME1 1
NAME1 1
NAME1 1
NAME1 1
NAME1 2
NAME1 2
NAME1 2
NAME1 2
NAME1 2
NAME1 3
NAME1 3
NAME2 1
NAME2 1
NAME2 1
NAME2 1
NAME2 1
NAME2 2
NAME3 1
NAME3 1
NAME4 1
NAME4 1
NAME4 1
NAME4 1
NAME4 1
NAME4 2
NAME4 2
NAME4 2
|
How can I do this using ICETOOL? |

The trick is to use START and INCR of the SEQNUM keyword, and then cut the last digit:
| Code: |
SORT FIELDS=(1,5,CH,A)
OUTREC OVERLAY=(7:SEQNUM,15,ZD,START=10,INCR=2,RESTART=(1,5))
OUTFIL FNAMES=OUT,OVERLAY=(21:X)

Hi,
Can you please explain how the above sort works - like what does START,INCR and RESTART works here.
Thanks. |

Hi,
Given the input I posted, the SEQNUM,15,ZD adds a 15 digit sequence number it in position 7. The sequence number starts at 10 (START) and is incremented by 2 (INCR) for each record. However when the key (in position 1 to 5) breaks (RESTART), the sequence number is reset (to 10, which is the starting number in this case). After the OUTREC OVERLAY, this is how it looks:
| Code: |
----+----1----+----2----+
NAME1 000000000000010
NAME1 000000000000012
NAME1 000000000000014
NAME1 000000000000016
NAME1 000000000000018
NAME1 000000000000020
NAME1 000000000000022
NAME1 000000000000024
NAME1 000000000000026
NAME1 000000000000028
NAME1 000000000000030
NAME1 000000000000032
NAME2 000000000000010
NAME2 000000000000012
NAME2 000000000000014
NAME2 000000000000016
NAME2 000000000000018
NAME2 000000000000020
NAME3 000000000000010
NAME3 000000000000012
NAME4 000000000000010
NAME4 000000000000012
NAME4 000000000000014
NAME4 000000000000016
NAME4 000000000000018
NAME4 000000000000020
NAME4 000000000000022
NAME4 000000000000024 |
The OUTFIL OVERLAY then clears position 21, that is, cuts the last digit of the sequence number, and you're done. :-)
