Hi All,

I have 3 files, one with lrecl 20, the 2nd one with lrecl 65 the third with lrecl = 30. I need to merge all these files into one with lrecl = 65.

This can be done by first converting lrecl 20 file to lrecl =65 by padding spaces in the end of each record and so on...but then this involves multiple steps.

Can we do this in one single sort step??

Something like

Code:


//STEP01   EXEC PGM=SORT                             
//SYSOUT   DD SYSOUT=*                               
//SYSPRINT DD SYSOUT=*                               
//SORTIN   DD DSN=file1,DISP=SHR  (lrecl=20)     
//         DD DSN=file2,DISP=SHR       (lrecl=65)
//         DD DSN=file3,DISP=SHR       (lrecl=30)
//SORTOUT  DD DSN=output file,                   
//     DISP=(NEW,CATLG,DELETE),                       
//     SPACE=(CYL,(3,5),RLSE),                       
//     DCB=(LRECL=65,RECFM=VB,BLKSIZE=0)             
//SYSIN    DD *                                       
  SORT FIELDS=COPY   
 Some other parameters.....                               
/*                                               
     




Thanks,
Deepesh

Deepesh,

The following DFSORT/ICETOOL JCL will give you desired results. If you syncsort at your shop then change the pgm name to synctool.Make sure that you have DISP=MOD for the Output dataset.

Code:

//STEP0100 EXEC PGM=ICETOOL
//TOOLMSG  DD SYSOUT=*                               
//DFSMSG   DD SYSOUT=*                               
//IN1      DD DSN=YOUR LRECL OF 20 FILE,
//            DISP=SHR
//IN2      DD DSN=YOUR LRECL OF 30 FILE,
//            DISP=SHR
//IN3      DD DSN=YOUR LRECL OF 65 FILE,
//            DISP=SHR
//OUT      DD DSN=output file,                   
//            DISP=(MOD,CATLG,DELETE),
//            UNIT=SYSDA,
//            SPACE=(CYL,(X,Y),RLSE)
//TOOLIN   DD *
  COPY FROM(IN1) TO(OUT) USING(CTL1)
  COPY FROM(IN2) TO(OUT) USING(CTL2)
  COPY FROM(IN3) TO(OUT)
//CTL1CNTL DD *
  OUTREC FIELDS=(1,20,     $ COPY 20 BYTES AS IS FROM IN1
                 65:X)     $ PAD SPACES UPTO 65 BYTES
//CTL2CNTL DD *
  OUTREC FIELDS=(1,30,     $ COPY 30 BYTES AS IS FROM IN2
                 65:X)     $ PAD SPACES UPTO 65 BYTES
/*                             


Hope this helps...

Cheers
