I think I saw a solution on this board, but can't find out now. Here is what I am trying (the reverse of Combine multiple records into one record listed in dfsort tricks)

input LRECL 250
------
Code:

Record 1Record 2Record 3
Record 4Record 5Record 6
Record 7Record 8

output LRECL 80
Code:

-------
Record 1
Record 2
Record 3
Record 4
Record 5
Record 6
Record 7
Record 8

Sreejith,

The following DFSORT JCL will give you the desired results. I assumed that you don't want to split the record if it has spaces.Since there are 3 different chunks of 80 byte data to check , the unique combinations will be 3 factorial which is 6. so we check for the 6 possible values and write out the records. These checks are to ensure that you don't write out blank records.

Code:

//STEP0100 EXEC PGM=SORT                                       
//SYSOUT   DD SYSOUT=*                                         
//SORTIN   DD DSN=Yu=our 250 byte input file,DISP=SHR
//SORTOUT  DD SYSOUT=*                                         
//SYSIN    DD *                                                 
  SORT FIELDS=COPY                                             
  INREC IFTHEN=(WHEN=INIT,BUILD=(1,240,C'111')),               
  IFTHEN=(WHEN=(001,1,CH,EQ,C' '),OVERLAY=(241:C'0'),HIT=NEXT),
  IFTHEN=(WHEN=(081,1,CH,EQ,C' '),OVERLAY=(242:C'0'),HIT=NEXT),
  IFTHEN=(WHEN=(161,1,CH,EQ,C' '),OVERLAY=(243:C'0'))           
                                                               
  OUTFIL IFOUTLEN=80,OMIT=(241,3,ZD,EQ,0),                     
  IFTHEN=(WHEN=(241,3,ZD,EQ,001),BUILD=(161,80)),               
  IFTHEN=(WHEN=(241,3,ZD,EQ,010),BUILD=(81,80)),               
  IFTHEN=(WHEN=(241,3,ZD,EQ,011),BUILD=(81,80,/,161,80)),       
  IFTHEN=(WHEN=(241,3,ZD,EQ,100),BUILD=(1,80)),                 
  IFTHEN=(WHEN=(241,3,ZD,EQ,101),BUILD=(1,80,/,161,80)),       
  IFTHEN=(WHEN=(241,3,ZD,EQ,110),BUILD=(1,80,/,81,80)),         
  IFTHEN=(WHEN=(241,3,ZD,EQ,111),BUILD=(1,80,/,81,80,/,161,80))

Kolusu,
Thanks very much. As usual it worked very well.

The actual data length is 230 in my case and the third split neatly came out with 10 spaces at the end.

Sreejith,

Glad it worked. You mentioned that your input LRECL is 250 in your initial post.
