Hi,

I had a input file of LRECL=200 and RECFM=FB.
I want to copy the records from this file to another file which is of LRECL=1000 and RECFM=FB moving NULL value from 201 onwards. How it can be done.

I tried this way but it didn't worked.
Code:

//STEP010  EXEC PGM=ICETOOL                                   
//TOOLMSG  DD SYSOUT=*                                         
//DFSMSG   DD SYSOUT=*                                         
//SYSOUT   DD SYSOUT=*                                         
//SYSUDUMP DD SYSOUT=C                                         
//SYSPRINT DD SYSOUT=*                                         
//INPUT    DD DSN=INPUT.FILE.LEN200,DISP=SHR
//OUTPUT   DD DSN=OUTPUT.FILE.LEN1000,       
//             DISP=(,CATLG,DELETE),                       
//             RECFM=FB,LRECL=1000,SPACE=(CYL,(500,500),RLSE)
//TOOLIN   DD *                                               
  COPY FROM(INPUT) TO(OUTPUT) USING(CTL1)                     
/*                                                             
//CTL1CNTL DD *                                               
  OUTFIL FNAMES=OUTPUT,REMOVECC                               
  OUTREC FIELDS=(1:1,200,201:X'00',LENGTH=800)                   
/*                                                             


If i give 201:x'00000000000000000.....' till 1600 zeroes it will default NULL in 800 bytes. But i want in simpler way.
Is there any other way to move NULL values from 201 to 1000 position of my output file.

Here's a DFSORT job that will do what you asked for:

Code:

//S1    EXEC  PGM=ICEMAN
//SYSOUT    DD  SYSOUT=*
//SORTIN   DD DSN=INPUT.FILE.LEN200,DISP=SHR
//SORTOUT  DD DSN=OUTPUT.FILE.LEN1000,
//             DISP=(,CATLG,DELETE),
//             SPACE=(CYL,(500,500),RLSE)
//SYSIN    DD    *
  OPTION COPY
  INREC BUILD=(1,200,800Z)
/*


You can use 800X'00' instead of 800Z if you prefer.
