ibmlearner,

The select operator of DFSORT can do that very easily

Code:

//STEP0100 EXEC PGM=ICETOOL                               
//TOOLMSG  DD SYSOUT=*                                   
//DFSMSG   DD SYSOUT=*                                   
//IN       DD *                                           
11111                                                     
11111 - REC2                                             
11111 - REC3                                             
22222                                                     
33333                                                     
33333 - REC2                                             
//OUT      DD SYSOUT=*                                   
//DUPS     DD SYSOUT=*                                   
//TOOLIN   DD *                                           
  SELECT FROM(IN) TO(OUT) ON(01,5,CH) FIRST DISCARD(DUPS)
/*


The out file will have

Code:

11111
22222
33333


The DUps file will have
Code:

11111 - REC2
11111 - REC3
33333 - REC2


If you want the unique keys in one file and all the duplicates in another file then use the following JCL

Code:

//STEP0100 EXEC PGM=ICETOOL                               
//TOOLMSG  DD SYSOUT=*                                     
//DFSMSG   DD SYSOUT=*                                     
//IN       DD *                                           
11111                                                     
11111 - REC2                                               
11111 - REC3                                               
22222                                                     
33333                                                     
33333 - REC2                                               
//OUT      DD SYSOUT=*                                     
//DUPS     DD SYSOUT=*                                     
//TOOLIN   DD *                                           
  SELECT FROM(IN) TO(OUT) ON(01,5,CH) NODUPS DISCARD(DUPS)
/*



The out file will have

Code:

22222


The DUps file will have
Code:

11111         
11111 - REC2 
11111 - REC3 
33333         
33333 - REC2
