Hi,
I have the following requirement.
I have a sequential file of length 10. The first seven digits are account numbers.The file has duplicate account numbers. However, the last 3 digits are different for the records.
The input file is as shown:
7046000034AAA
7046000034CCC
7045555555FFF
7046000034BBB
7044444444DDD
I want the output to show the following:
7044444444DDD
7045555555FFF
7046000034AAA
7046000034CCC
7046000034BBB
When I sorted on account numbers in ascending order, the values for account number 7046000034 is coming in order AAA, BBB and then CCC. I want to keep the order as (AAA,CCC,BBB). I am not sure if I can use ICETOOL with select option and then use the word keepbase. Please advise.
Regards,
Sandy. |

Sandy,
Use OPTION EQUALS, it specifies that the original sequence must be preserved.
| Code: |
OPTION EQUALS
SORT FIELDS=(1,7,ZD,A) |
Output
| Code: |
7044444444DDD
7045555555FFF
7046000034AAA
7046000034CCC
7046000034BBB

Thanks, |

Frank/Kolusu,
if there is no sign-bits involved with numbers, I always define the field as CH.
I would have used the following:
SORT FIELDS=(1,7,CH,A)
is there any advantage to using a numeric unsigned datatype in the sort parm? i.e. UFF or BI over CH
is there any disadvantage to using numeric signed datatype for unsigned data? i.e. ZD when there is no sign? |

Dick Brenholtz,
Just for the clarification on my proposed solution, OP said
| Quote: |
| The first seven digits are account numbers. |
Since she/he mentioned digits, I have used ZD in solution.
Thanks, |

In general, for unsigned data, BI is the most efficient format. CH is equivalent to BI as long as options like LOCALE and CHALT are not in effect. ZD is not as efficient as BI or CH. UFF is not as efficient as ZD. |
