Hi,

Can some one please help me with the bleow. Record 1(Positions 4-8) in first file should be overlaid with second file(Positions 1-5) and write into output file. There is no matching criteria between these files. Input files will always have same number of records.

Input File 1
Code:

001CARD0.........
002CARD1.........
003CARD2.........
004CARD3.........
005CARD4.........


Input File 2

Code:

CARD5
CARD6
CARD7
CARD8
CARD9


Output File

Code:

001CARD5.........
002CARD6.........
003CARD7.........
004CARD8.........
005CARD9.........

erasani,


You can use Joinkeys to create a psuedo key and merge based on that.

Untested DFSORT JCL which will give you the desired results. Since you haven't provided DCB properties of the input files I assumed them to be FB recfm and 80 bytes in length
Code:

//STEP0100 EXEC PGM=SORT                         
//SYSOUT   DD SYSOUT=*                           
//INA      DD *                                 
001CARD0.........                               
002CARD1.........                               
003CARD2.........                               
004CARD3.........                               
005CARD4.........                               
//INB      DD *                                 
CARD5                                           
CARD6                                           
CARD7                                           
CARD8                                           
CARD9                                           
//SORTOUT  DD SYSOUT=*                           
//SYSIN    DD *                                 
  OPTION COPY                                   
  JOINKEYS F1=INA,FIELDS=(81,8,A),SORTED,NOSEQCK
  JOINKEYS F2=INB,FIELDS=(06,8,A),SORTED,NOSEQCK
  REFORMAT FIELDS=(F1:01,03,                     
                   F2:01,05,                     
                   F1:09,72)                     
/*                                               
//JNF1CNTL DD *                                 
  INREC OVERLAY=(81:SEQNUM,8,ZD)                 
/*                                               
//JNF2CNTL DD *                                 
  INREC BUILD=(01,05,SEQNUM,8,ZD)               
/*
