Hi.

My requirement is jcl to do like this:

input file : fb, lrec=7

2222600
2222250
3333700
3333500
7777100

output file: fb, lrec=8

22220850
33331200
77770100


If starting 4 bytes are same in input file we have to sum next 3 bytes and write one record in output file.

Code:

Here's another way to do it with DFSORT using copy which is more efficient than sort (assuming that your records are already in sorted order as shown in your example - if not you can add a SORT statement):

Code:

//S1    EXEC  PGM=ICEMAN                             
//SYSOUT    DD  SYSOUT=*                             
//SORTIN DD *                                         
2222600                                               
2222250                                               
3333700                                               
3333500                                               
7777100   
/*                                           
//SORTOUT DD SYSOUT=*                                 
//SYSIN    DD    *                                   
  OPTION COPY                                         
  OUTFIL REMOVECC,NODETAIL,                           
    SECTIONS=(1,4,                                   
      TRAILER3=(1,4,TOT=(5,3,ZD,TO=ZD,LENGTH=4)))
