Hi,

My file has 3 type of records.

Header starts with '01', detailed starts with '02' and Trailer starts with '03'. Since multiple source sends the files, one of our process has multiple header and multiple trailer as input.

But, I want to sort only detailed records based on Acct Id ( 4th pos 36 length ).

The header and trailer records should not be sorted and remain as it is. Right now I split these into 3 files and sort only detailed records and then concatenate. But I am expecting solution in a single SORT step.

I saw this from ICETOOL

Code:

//S1 EXEC PGM=ICETOOL
//TOOLMSG DD SYSOUT=*
//DFSMSG DD SYSOUT=*
//IN1 DD DSN=... input file
//OUT1 DD DSN=... output file
//TOOLIN DD *
DATASORT FROM(IN1) TO(OUT1) HEADER(2) TRAILER(3) USING(CTL1)
//CTL1CNTL DD *
SORT FIELDS=(4,36,CH,A)
/*

But this work only if we know the number of headers and trailers that will come in a file.

Help pls

Sample Input
Code:

01header03
01header05
01header03
01header02
02C0000012
02C0000010
02C0000022
02C0000002
02C0000011
02C0000001
02C0000008
02C0000006
02C0000004
03Trailer02
03Trailer01
03Trailer03


Expected Output
Code:

01header03
01header05
01header03
01header02
02C0000001
02C0000002
02C0000004
02C0000006
02C0000008
02C0000010
02C0000011
02C0000012
02C0000022
03Trailer02
03Trailer01
03Trailer03


Thanks

arvibala,

Assuming the LRECL is 80 and RECFM FB, the following DFSORT JCL will give you the desired results

Code:

//STEP0100 EXEC PGM=SORT                             
//SYSOUT   DD SYSOUT=*                               
//SORTIN   DD *                                       
01HEADER03                                           
01HEADER05                                           
01HEADER03                                           
01HEADER02                                           
02C0000012                                           
02C0000010                                           
02C0000022                                           
02C0000002                                           
02C0000011                                           
02C0000001                                           
02C0000008                                           
02C0000006                                           
02C0000004                                           
03TRAILER02                                           
03TRAILER01                                           
03TRAILER03                                           
//SORTOUT  DD SYSOUT=*                               
//SYSIN    DD *                                       
  INREC IFTHEN=(WHEN=INIT,OVERLAY=(81:1,2,4,36)),     
  IFTHEN=(WHEN=(1,2,SS,EQ,C'01,03'),OVERLAY=(83:36X))
  SORT FIELDS=(81,38,CH,A),EQUALS                     
  OUTREC BUILD=(1,80)
