Hi,

My Input File,
Code:
----+----1----+----2----+----3----+
G3A8420CFP478296..|G3A8420CFP478296
G3A8838FFS855437..?G3A3707FFS855437
G3G3835FFS595971...G3B4512FFS595971
G3!4512CC0W3000K..±G3B4512CC0W3000K
G3!4512CC0W3087K..±G3B4512CC0W3087K
G3!4512CC0W3320G..±G3B4512CC0W3320G
G3!4512CC0W3331G..±G3B4512CC0W3331G
G3B1013FFT161151...G3B2203FFT161151


Output File:
Code:
----+----1----+----2----+----3----+
G3A8420CFP478296..|G3A8420CFP478296
G3A8838FFS855437..?G3A3707FFS855437
G3B1013FFT161151...G3B2203FFT161151


In the output file created, it should not contain the records in which the 3rd AND 22nd COLUMN are different. Else the whole record should be copied in output file. The input file can have duplicates.

The input and output file LRECL is 35. The 3rd and 22nd position can hav special characters also.

Can this be done by DFSORT?

I believe we can get the output by using SPLICE option. Currently I am trying by level best to get the output using the SPLICE option in ICETOOL.

Can any one of please guide me to get the expected results?

I've assumed that the records are FB
Code:

//CONCAT   DD DSN=&&TEMP01,DISP=(MOD,PASS,DELETE),     
//            SPACE=(TRK,(10,10),RLSE),                 
//            RECFM=FB,LRECL=80                         
//CONCAT2  DD DSN=&&TEMP02,DISP=(MOD,PASS,DELETE),     
//            SPACE=(TRK,(10,10),RLSE),                 
//            RECFM=FB,LRECL=80                         
//OUT      DD SYSOUT=*                                 
//TOOLIN   DD *                                         
*                                                       
  COPY FROM(IN1) TO(CONCAT) USING(CPY1)                 
*                                                       
  COPY FROM(IN1) TO(CONCAT) USING(CPY2)                 
*                                                       
  SPLICE FROM(CONCAT) TO(CONCAT2) ON(37,1,CH) WITH(38,1)
*                                                       
  COPY FROM(CONCAT2)  TO(OUT) USING(CPY3)               
/*                                                     
//CPY1CNTL DD *                                         
  OUTREC BUILD(1,35,X,3,1)                             
/*                           
//CPY2CNTL DD *               
  OUTREC BUILD(1,35,X,22,1,X)
/*                           
//CPY3CNTL DD *               
  OUTREC BUILD(1,35)         

Result
Code:

G3!4512CC0W3000K..±G3B4512CC0W3000K
G3A8420CFP478296..|G3A8420CFP478296
G3B1013FFT161151...G3B2203FFT161151

kaleelahamed,

The below SORT job does what you asked for.
Code:
//STEP1    EXEC PGM=ICEMAN                                 
//SYSOUT   DD SYSOUT=*                                     
//SORTOUT  DD SYSOUT=*                                     
//SORTIN   DD DSN=your.input.file....>FB,LRECL=35                                           
//SYSIN    DD *                                           
  INREC IFTHEN=(WHEN=INIT,OVERLAY=(36:C'0')),             
        IFTHEN=(WHEN=(3,1,CH,NE,22,1,CH),OVERLAY=(36:C'1'))
  OPTION COPY                                             
  OUTFIL OMIT=(36,1,CH,EQ,C'1'),BUILD=(1,35)               

SORTOUT
Code:
G3A8420CFP478296..|G3A8420CFP478296
G3A8838FFS855437..?G3A3707FFS855437
G3B1013FFT161151...G3B2203FFT161151


expat,
The 3rd and 22nd characters in the first record of your output differ.

Thanks,
Arun

kaleelahamed,

It is a simple case of using an OMIT cond. expat and arcvns made it complicated. The following DFSORT JCL will give you the desired results
Code:

//STEP0100 EXEC PGM=ICEMAN             
//SYSOUT   DD SYSOUT=*                 
//SORTIN   DD *                       
G3A8420CFP478296..|G3A8420CFP478296   
G3A8838FFS855437..?G3A3707FFS855437   
G3G3835FFS595971...G3B4512FFS595971   
G3!4512CC0W3000K..±G3B4512CC0W3000K   
G3!4512CC0W3087K..±G3B4512CC0W3087K   
G3!4512CC0W3320G..±G3B4512CC0W3320G   
G3!4512CC0W3331G..±G3B4512CC0W3331G   
G3B1013FFT161151...G3B2203FFT161151   
//SORTOUT  DD SYSOUT=*                 
//SYSIN    DD *                       
  SORT FIELDS=COPY                     
  OMIT COND=(3,1,CH,NE,22,1,CH)       
/*


Hope this helps...

Cheers

Really? This syntax has been part of DFSORT for decades. Perhaps you might want to go through "z/OS DFSORT: Getting Started" to see what else you're not aware of. You can find it at:
