I am facing a problem can anybody please look into this and help me out, I tried searching but failed to get the answer.

Below is the test data of my input file:

0000ABCDEF
ACCEPTED
11110002000ADDICT
44420002000ADDICT
22211110002000ANOWHS
44420002000ADDICT


My requirement is to have the first two records as it is (order should be preserved) and the rest of the records to be sorted
on first 3 bytes. I could achieve this in 3 steps, can anybody help me in reducing the number of steps?

The output file should look like below:


0000ABCDEF
ACCEPTED
11110002000ADDICT
22211110002000ANOWHS
44420002000ADDICT
44420002000ADDICT


Thanks,
Temu.

Here's a DFSORT/ICETOOL job that will do what you asked for in one pass/step.

Code:

//S1   EXEC  PGM=ICETOOL
//TOOLMSG   DD  SYSOUT=*
//DFSMSG    DD  SYSOUT=*
//IN DD DSN=...  input file (FB)
//OUT DD DSN=...  output file (FB)
//TOOLIN DD *
DATASORT FROM(IN) TO(OUT) HEADER(2) USING(CTL1)
/*
//CTL1CNTL DD *
  SORT FIELDS=(1,3,CH,A)
/*


For complete details on the DATASORT function and the other new functions available with DFSORT PTF UK90013 (July, 2008), see:

Assuming the input file is FB/80, try this alternate solution:

Code:

//S1    EXEC PGM=SORT   
//SORTIN  DD DSN=input.file,...                 
//SORTOUT DD DSN=output.file,...
//SYSOUT  DD SYSOUT=*                         
//SYSIN   DD *                                                 
 INREC IFTHEN=(WHEN=INIT,OVERLAY=(81:SEQNUM,8,ZD)),         
       IFTHEN=(WHEN=(81,8,ZD,GT,2),OVERLAY=(81:C'99999999'))
 SORT FIELDS=(81,8,CH,A,1,3,CH,A)                           
 OUTREC FIELDS=(1,80)                                       
/*
