Hi,

I am not sure if this is possible in SORT or not.

I have an input file as shown below:
----|----1----|----2----|----3----|----4----|----5----|----6----|----7----
AAAAAAAAAA COUNTX 25
BBBBBBBBBB COUNTP 50
CCCCCCCCCC COUNTU 75
AAAAAAAAAA COUNTY 75
BBBBBBBBBB COUNTQ 100
CCCCCCCCCC COUNTV 25

My output file should be:
----|----1----|----2----|----3----|----4----|----5----|----6----|----7----
AAAAAAAAAA COUNTX 25
BBBBBBBBBB COUNTP 50
CCCCCCCCCC COUNTU 75
AAAAAAAAAA COUNTY 75
PERCENTAGE 300.00
BBBBBBBBBB COUNTQ 100
PERCENTAGE 200.00
CCCCCCCCCC COUNTV 25
PERCENTAGE 33.33

Basically I need to find out the % of the counts given in record 4 against the record 1 of input file. ie., 75*100/25 = 300.00
Similarly record 5 (Vs) record 2 and record 6 (Vs) record 3.

This percentage should get written in the output file as shown above.

Kindly do the needful to resolve this problem.

Thanks,
Naveen.

The following DFSORT/ICETOOL JCL will give you the desired results. I assumed that your input is RECFM FB and 80 bytes in length.

Code:

//STEP0100 EXEC PGM=ICETOOL                                         
//TOOLMSG  DD SYSOUT=*                                               
//DFSMSG   DD SYSOUT=*                                               
//IN       DD *                                                     
AAAAAAAAAA COUNTX  25                                               
BBBBBBBBBB COUNTP  50                                               
CCCCCCCCCC COUNTU  75                                               
AAAAAAAAAA COUNTY  75                                               
BBBBBBBBBB COUNTQ 100                                               
CCCCCCCCCC COUNTV  25                                               
//T1       DD DSN=&&T1,DISP=(,PASS),SPACE=(CYL,(1,1),RLSE)           
//OUT      DD SYSOUT=*                                               
//TOOLIN   DD *                                                     
  SORT FROM(IN) USING(CTL1)                                         
  SORT FROM(T1) USING(CTL2)

  IFTHEN=(WHEN=(89,1,ZD,EQ,2),OVERLAY=(93:19,3,SFF,ZD,LENGTH=3))     
                                                                     
  OUTFIL FNAMES=T1,REMOVECC,                                         
  SECTIONS=(1,10,                                                   
  TRAILER3=('PERCENTAGE',81:MAX=(81,8,ZD,M11,LENGTH=8),             
            90:TOT=(90,3,ZD,M11,LENGTH=3),                           
            93:TOT=(93,3,ZD,M11,LENGTH=3),                           
            'Y'))

  INREC IFTHEN=(WHEN=(96,1,CH,EQ,C'Y'),                             
  OVERLAY=(81:+1,ADD,81,8,ZD,M11,LENGTH=8,                           
           12:+10000,MUL,93,3,ZD,DIV,90,3,ZD,EDIT=(IIT.TT)))         
  SORT FIELDS=(81,8,CH,A)                                           
  OUTFIL FNAMES=OUT,BUILD=(1,80)                                     
/*                                                                   


the output from this job is

Code:

AAAAAAAAAA COUNTX  25   
BBBBBBBBBB COUNTP  50   
CCCCCCCCCC COUNTU  75   
AAAAAAAAAA COUNTY  75   
PERCENTAGE 300.00       
BBBBBBBBBB COUNTQ 100   
PERCENTAGE 200.00       
CCCCCCCCCC COUNTV  25   
PERCENTAGE  33.33

Hi,

Thanks a lot for your time and the code works fine. The idea is great.
But now I am facing a problem while getting a Count of Zero in the input file as shown below:
----|----1----|----2----|----3----|----4----|----5----|----6----|----7----
AAAAAAAAAA COUNTX 0
BBBBBBBBBB COUNTP 0
CCCCCCCCCC COUNTU 75
AAAAAAAAAA COUNTY 75
BBBBBBBBBB COUNTQ 100
CCCCCCCCCC COUNTV 25

The error message is 'INREC ARITHMETIC OVERFLOW'.
Kindly suggest me if you have any idea to resolve this.

Thanks,

The arthimetic overflow is because you are dividing by zero which is infinity. Incase of zero how would you lke to calcuate the percentage?

Hi,
In case of a zero, the percentage can be a zero.
Thanks,

nave11,

Change your CTL2CNTL control cards to the following which will give you the desired results

Code:

//CTL2CNTL DD *                                               
  OPTION EQUALS                                               
  INREC IFTHEN=(WHEN=(96,1,CH,EQ,C'Y',AND,90,3,ZD,GT,0),     
  OVERLAY=(81:+1,ADD,81,8,ZD,M11,LENGTH=8,                   
           12:+10000,MUL,93,3,ZD,DIV,90,3,ZD,EDIT=(IIT.TT))),
  IFTHEN=(WHEN=(96,1,CH,EQ,C'Y',AND,90,3,ZD,EQ,0),           
  OVERLAY=(81:+1,ADD,81,8,ZD,M11,LENGTH=8,12:C'000.00'))     
  SORT FIELDS=(81,8,CH,A)                                     
  OUTFIL FNAMES=OUT,BUILD=(1,80)                             
/*
