I have a flat file like shown below:
Code:
Item_Desc                 Order_ID              Quantity
--------------------------------------------------------------
Sofa      Or1      75
Sofa      Or2      100
      
Chair      Or3      90
Chair      Or4      100
      
Table      Or5      67
      
Sheet      Or6      78
      
Blanket      Or7      90
      
Pillow      Or8      60
Pillow      Or9      100

I want to create an output file from this input file where the rows need to be sorted after computing the average in case of Item_Desc occuring more than once. For items occuring only once, average quantity = quantity.

Basically, I want output for this case as follows :
Code:
Item Desc                 Order_ID             Quantity
-----------------------------------------------------------
Chair      Or3      80
Chair      Or4      100

Blanket      Or7      90

Pillow      Or8      60
Pillow      Or9      100

Sheet      Or6      78

Sofa      Or1      75
Sofa      Or2      100
      
Table      Or5      67


Please suggest a solution for this problem using either ICETOOL or SORT.

Thanks

After 5 years of reading the forum you still do not use code tags or provide the basic information asked for in almost every sort topic.

I edited the post for the code tags, but H311 will freeze before I waste time reformatting icon_biggrin.gif

AVG
specifies that an edited or converted average, for the values of a numeric input field in all data records of the report, is to appear in the report record. The average (or mean) is calculated by dividing the total by the count and rounding down to the nearest integer. For example:

10:'Average revenue: ',AVG=(25,5,PD,M5))

I apologize for the clumsy representation of information.
However, gylbharat, can you please help me with a complete control card of the AVG computation you mentioned below. Please let me know if you need more information on the problem I posted.

afroz.alam,

Your output does not match the specifications. You say you wanted to sort the records by descending average. so how did the PILLOW with an average of 80 (100+60 =160/2 =80) get sorted before SOFA with an average of 87.5 (75+100 =175/2 = 87.5) ?? I am guessing that they are typos. Here is DFSORT JCL which will give you the desired results.

Assumptions :

LRECL = 80
RECFM = FB
Item_Desc = 15 bytes starts at pos 1
Order_ID = 10 bytes starts at pos 16
Quantity = 05 bytes starts at pos 26 with leading zeroes supressed.

Use the same input file for both DD's INA and INB.

Code:

//STEP0100 EXEC PGM=SORT           
//SYSOUT   DD SYSOUT=*             
//INA      DD *                   
----+----1----+----2----+----3----+
SOFA           OR1          75     
SOFA           OR2         100     
CHAIR          OR3          90     
CHAIR          OR4         100     
TABLE          OR5          67     
SHEET          OR6          78     
BLANKET        OR7          90     
PILLOW         OR8          60     
PILLOW         OR9         100     
//INB      DD *                   
SOFA           OR1          75     
SOFA           OR2         100     
CHAIR          OR3          90     
CHAIR          OR4         100     
TABLE          OR5          67     
SHEET          OR6          78     
BLANKET        OR7          90     
PILLOW         OR8          60     
PILLOW         OR9         100     
//SORTOUT  DD SYSOUT=*             
//SYSIN    DD *                                                   
  JOINKEYS F1=INA,FIELDS=(01,15,A)                                 
  JOINKEYS F2=INB,FIELDS=(01,15,A)                                 
  REFORMAT FIELDS=(F1:1,80,F2:16,9)                               
  INREC OVERLAY=(91:(81,5,ZD,MUL,+100),DIV,87,3,ZD,EDIT=(TTTTT.TT))
  SORT FIELDS=(91,8,CH,D,1,15,CH,A),EQUALS                         
  OUTREC BUILD=(1,80)                                             
//*
//JNF2CNTL DD *                                                   
  INREC BUILD=(1,15,26,5,UFF,M11,LENGTH=5,C' 001')                 
  SUM FIELDS=(16,5,22,3),FORMAT=ZD                                 
//*


The output from this is

Code:

----+----1----+----2----+----3----+
CHAIR          OR3          90
CHAIR          OR4         100
BLANKET        OR7          90
SOFA           OR1          75
SOFA           OR2         100
PILLOW         OR8          60
PILLOW         OR9         100
SHEET          OR6          78
TABLE          OR5          67

You are using SYNCSORT not DFSORT.

I am not sure if our shop has or supports DFSORT. Can you please provide control card supported by SYNCSORT?

there was a thread just the other day, where someone was using syncsort with joinkeys. syncsort has other syntax or can't use jfn1cntl or refomat or something.

i use dfsort so didnot bother to remember,
but, looking thru posts for the last couple of days will provide the answer,
since the ts obviously does not feel compelled to consult a manual.
