Arithmetic operations using syncsort

Postby ibmmf4u » Fri Mar 21, 2014 12:53 am

Hi All,

Here is my requirement. I would basically like to evaluate the percentage of two fields in a file and write it to an output file.

Input file is a follows:-

col1;            col2;            col3;
   A;           22.32;           11.32;
   B;        11111.99;        10920.35;
   C;         3567.23;           38.60;
   D;          760.25;          575.57;



It should basically be calculating the difference between col2 and col 3 ( Res1=col2-col3) and divide by col3 ( (res1/col3)*100) to get the percentage.

Output file is as follows :-

col1;            col2;            col3;              col4;
   A;           22.32;           11.32;0.9717314487632509 
   B;        11111.99;        10920.35;0.0175488880850888 
   C;         3567.23;           38.60;91.41528497409326   
   D;          760.25;          575.57;0.3208645342877495 


Can some one help me in achieving it.

Thanks in advance.

P.S. I tried doing it in phase by phase but unable to achieve it.

Hello,

Suggest you post the code you tried and explain what did not work.

Posting it didn't work is the biggest waste of time in the forum . . . You need to show what didn't work - diagnostic message, failed run, not the desired results, etc.
Hope this helps,
d.sch.

Hi Dick,

Pasted below is the piece of code which i tried running in Phases.

The resultant filed in first which phase which the difference between (col2-col3) is a 16 byte field of which the last two positions are reserved for the decimal places i have done it with the help of EDIT ( as i couldn't able to obtain it automatically).

//STEP010  EXEC PGM=SORT                                       
//SORTIN   DD DSN=INPUT.FILE,DISP=SHR               
//SORTOUT  DD DSN=TEMP.FILE,                       
//            DISP=(NEW,CATLG,DELETE),                         
//            SPACE=(CYL,(10,20),RLSE),                         
//            DCB=(RECFM=FB,LRECL=250)                         
//SYSOUT   DD SYSOUT=*                                         
//SYSIN    DD *                                                 
  SORT  FIELDS=COPY -                                           
  OUTREC FIELDS=(1,40,4X,                                       
               (6,16,UFF,SUB,23,16,UFF),EDIT=(TTTTTTTTTTTTT.TT))
//*                                                             


Output:-

   A;           22.32;           11.32;     0000000000011.00
   B;        11111.99;        10920.35;     0000000000191.64
   C;         3567.23;           38.60;     0000000003528.63
   D;          760.25;          575.57;     0000000000184.68


And later tried to divide the resultant value with the col3 but couldn't able to get the exact results ( missing the decimal points am not sure if its beacuse of UFF)

//STEP040  EXEC PGM=SORT                         
//SORTIN   DD DSN=TEMP.FILE,DISP=SHR
//SORTOUT  DD DSN=OUTPUT.FILE,         
//            DISP=(NEW,CATLG,DELETE),           
//            SPACE=(CYL,(10,20),RLSE),         
//            DCB=(RECFM=FB,LRECL=250)           
//SYSOUT   DD SYSOUT=*                           
//SYSIN    DD *                                 
  SORT  FIELDS=COPY -                           
  OUTREC FIELDS=(1,64,X,                         
           (45,16,UFF,DIV,23,16,UFF))           


Output:-

  A;           22.32;           11.32;     0000000000011.00              0
  B;        11111.99;        10920.35;     0000000000191.64              0
  C;         3567.23;           38.60;     0000000003528.63             91
  D;          760.25;          575.57;     0000000000184.68              0



Request you to kindly help me out :)

Thanks in advance!!

Hello ibmmf4u,

Here is an example that may be helpful to you:
//SORT1 EXEC PGM=SORT                                               
//SYSOUT  DD SYSOUT=*                                               
//SORTOUT DD SYSOUT=*                                               
//SORTIN  DD *                                                       
A       22.32    11.32                                               
B    11111.99 10920.35                                               
C     3567.23    38.60                                               
D      760.25   575.57                                               
//SYSIN   DD *                                                       
  SORT FIELDS=COPY                                                   
  OUTREC IFTHEN=(WHEN=INIT,                                         
     BUILD=(1,5,(((6,8,UFF,SUB,15,8,UFF),MUL,+10000),DIV,15,8,UFF))),
         IFTHEN=(WHEN=(16,1,CH,EQ,C' '),                             
         OVERLAY=(16:17,4,ZD,EDIT=(TT.TT))),                         
         IFTHEN=(WHEN=(16,1,CH,NE,C' '),                             
         OVERLAY=(14:14,7,ZD,DIV,+100,EDIT=(TT.TT)))         
/*       


This is the output produced by the step above:
A              97.17
B              01.75
C            91.4152
D              32.08

It may need to be tweaked to get the exact formatting of the output you desire, but its a good starting point.
