Hi all.

Code:

AAAAAA   11111111 222222222

No, you need a program.
JCL is for allocating resources and initiating programs.

It is not possible in JCL.

It is possible when using:
1) SYNCSORT or DFSORT utilities
2) code in REXX
3) code in COBOL
4) code in C/C++
……..
100500) code in almost any programming language, or tool.

JCL is the only one language which cannot do what you need.

Please post under right section of the forum .
If you know DFSORT/SYNCSORT then think about this approach.

If you do little more search you may get more similar results and then give a little twist as per your need and try. If you still face issues let us know we would try to help.

I guess that we will not see a solution from the TS here. It should look like this:
Code:
//WHATEVER EXEC PGM=ICEMAN
//SORTIN   DD *                                         
AAAAAA   11111111 222222222                             
AAAAAA   33333333 444444444                             
BBBBBB   11111111 555555555                             
CCCCCC   77777777 888888888                             
/*                                                     
//SYSOUT   DD SYSOUT=*                                 
//SORTOUT  DD SYSOUT=*                                 
//SYSIN    DD *                                         
  OPTION COPY                                           
  OUTFIL FNAMES=(SORTOUT),                             
    REMOVECC,                                           
    SECTIONS=(1,6,SKIP=1L,                             
      HEADER3=(1:C'Col1',10:C'Col2',19:C'Col3')),       
    BUILD=(1,80)                                       
  END                                                   
/*

Output:
Code:
****** ****************************
000001 Col1     Col2     Col3     
000002 AAAAAA   11111111 222222222
000003 AAAAAA   33333333 444444444
000004                             
000005 Col1     Col2     Col3     
000006 BBBBBB   11111111 555555555
000007                             
000008 Col1     Col2     Col3     
000009 CCCCCC   77777777 888888888

As a fool-proof, the SORT on SECTIONS columns needs to be added, I guess.
