My input file contains the below,

Code:

Field 1       Field 2
A                   1
A                   1
B                   1
B                   2
C                   1
C                   1
C                   2
D                   1


My output file should contain,

Code:

Field 1        Field 2
A                    1
A                    1
D                    1


I do not want records in my output which have DIFFERENT values in Field 2.

Please help on this using SORT/ICETOOL. Thanks in advance.

veeramanimurugesan,

How many different values does FIELD2 have? is it always just 1 and 2?

Field 2 could have multiple values. 1 and 2 was just a sample to understand the requirement. Field 2 values are unpredictable. It is actually a 9 character
field.

For example,
Field 1 - Client Number
Field 2 - Account Number

A single client can have multiple accounts. If he has DIFFERENT multiple accounts, then i need to eliminate those records. If he has 2 records with same accounts, then i can have him in output. Only clients with DIFFERENT accounts need to be filtered out.

Hi smijoss

Thanks for your response.

JOINKEYS wont work in my version of DFSORT. The sort version on mainframe here is Z/OS DFSORT V1R10.

Error :
COPY JKFROM TO(FILEOUT) USING(CTL2) 00240001
DFSORT CALL 0002 FOR COPY FROM JOINKEYS TO FILEOUT USING CTL2CNTL TERMINATED
OPERATION RETURN CODE: 16

Please advise.

Thanks ! I will test this with my actual data.

It would be very helpful if you could explain the logic in TOOLIN, CTL1CNTL, CTL2CNTL control cards OR some short notes on how did you arrive at the output.

i knew u would ask the icon_smile.gif

TOOLIN :
you code the commands here for ICETOOL as you do in SYSIN for sortcard

to understand the purpose of CTL1CNTL -
check the output file TEMP.TEST.TEST1


download DFSORT getting started pdf, its explained very well
