//*                                                                     
//TOOLMSG   DD  SYSOUT=*                                               
//DFSMSG    DD  SYSOUT=*                                               
//*                                                                     
//IN1       DD DSN=your.INPUT1,DISP=SHR                         
//IN2       DD DSN=your.INPUT2,DISP=SHR                         
//* 
//T1        DD DSN=&&T1,UNIT=SYSDA,SPACE=(CYL,(5,5)),DISP=(MOD,PASS)   
//*

  COPY FROM (IN1) TO (T1) USING CTL1
  COPY FROM (IN2) TO (T1) USING CTL1 
  SELECT FROM (T1) TO (OUT) ON(starting pos of key,length,CH) ALLDUPS                             /*

Souvik Upadhyay,

You don't need 3 steps to get the desired results. you can simply concatenate both the files and use the parm ALLDUPS on a SELECT statement.

Take a look at this topic

http://www.mvsforums.com/helpboards/viewtopic.php?t=9&highlight=alldups

You also might want to add a disclaimer for your DFSORT/ICETOOL solutions, as not all DFSORT/ICETOOL solutions are compatible with SYNCSORT/synctool.

Kolusu,
Sorry for the 3 steps when 1 was sufficient ... will keep this in mind ... Embarassed

And yes I will add a disclaimer that all ICETOOL are not compatible with SYNCTOOL ... the original poster did not specify whether he wanted DFSORT/ICETOOL or SYNCSORT/SYNCTOOL ...
