Hello there,

I want to use DFSORT to count the rows in each group which has the same value in Column 8-16. Could you please help?

My input file is as this -

Code:

111111  aaaaaaaaa
222222  aaaaaaaaa
333333  bbbbbbbbb
111111  aaaaaaaaa


If the data in column 8-16 are same but the data in column 1-6 are different, then count it. Then output the column 8-16 and the count number (with a space between them).

So the expected output file is -

Code:

aaaaaaaaa 2
bbbbbbbbb 1


This is because for 'aaaaaaaaa', 2 different value (111111 & 222222) can be found. and for 'bbbbbbbbb' only 1 value can be found.

Thanks a lot!!

Dragon_Lee,

Here is one traditional way of doing what you asked for. I'm sure with the latest version of DFSORT, you can accomplish this in just 1 pass.

Code:

//R010   EXEC  PGM=ICETOOL
//TOOLMSG  DD  SYSOUT=*                               
//DFSMSG   DD  SYSOUT=*                               
//INPUT    DD  *                                     
111111  AAAAAAAAA                                     
222222  AAAAAAAAA                                     
333333  BBBBBBBBB                                     
111111  AAAAAAAAA                                     
/*                                                   
//TEMP1    DD  DSN=&&T1,DISP=(,PASS)                 
//OUTPUT   DD  SYSOUT=*                               
//TOOLIN   DD  *                                     
  SELECT FROM(INPUT)  TO(TEMP1)  ON(1,17,CH)  FIRST   
  SORT   FROM(TEMP1)  TO(OUTPUT) USING(CTL1)         
//CTL1CNTL DD  *                                     
  INREC FIELDS=(1,17,2X,C'00000001')                 
  SORT FIELDS=(9,9,CH,A)                             
  SUM FIELDS=(20,8,ZD)                               
  OUTREC FIELDS=(9,9,2X,20,8)                         
/*                                                   


Hope this helps,

Thanks,
Phantom

Dragon,

Here's a DFSORT job that will do what you asked for in one pass. I assumed you wanted three digits with leading zeros for the count. If not, you can change the EDIT mask to give you what you want.

Code:

//S1    EXEC  PGM=ICEMAN
//SYSOUT    DD  SYSOUT=*
//SORTIN DD *
111111 aaaaaaaaa
222222 aaaaaaaaa
333333 bbbbbbbbb
111111 aaaaaaaaa
//SORTOUT DD SYSOUT=*
//SYSIN    DD    *
  SORT FIELDS=(8,9,CH,A,1,6,CH,A)
  SUM FIELDS=NONE
  OUTFIL REMOVECC,NODETAIL,
   SECTIONS=(8,9,
     TRAILER3=(8,9,X,COUNT=(EDIT=(TTT))))

Dragon_Lee,

Try this 1 step JCl which will give you the desired results

Code:

//STEP0100 EXEC PGM=SORT     
//SYSOUT   DD SYSOUT=*       
//SORTIN   DD *             
111111 AAAAAAAAA             
222222 AAAAAAAAA             
333333 BBBBBBBBB             
111111 AAAAAAAAA             
//SORTOUT  DD SYSOUT=*       
//SYSIN    DD *             
  SORT FIELDS=(8,8,CH,A,     
               1,6,CH,A)     
  SUM FIELDS=NONE           
  OUTFIL REMOVECC,NODETAIL, 
  SECTIONS=(8,16,           
  TRAILER3=(8,16,COUNT))
