Hi,

File is 850 bytes long

I need to populate Sequence Id ( Pos 352 to 360 ) based on some field Values ( explained below) and seq id is a numeric field and its sorted based on

Acct-Id 4th position 36 length
Tran-Id 164th position 36 length

File 1 : Header ( pos 1 - 2 = '01' )
File 2. If 829-830th position is 'D2', Seq Id should be '000000010'
File 3. If 829-830th position is 'I0 and 3rd position is 'C', Seq Id should be '000000020'
File 4. If 829-830th position is 'U1', Seq Id should be '000000030'
File 5. If 829-830th position is 'I0' and 3rd position is 'D' and 248 - 251 = 'ITFR' OR 'ETFR' , Seq Id should be '000000050'
File 6. If 829-830th position is 'I0' and 3rd position is 'D' and 248 - 251 = other than 'ITFR' OR 'ETFR' , Seq Id should be '000000040'
File 7 : Trailer ( pos 1 - 2 = '03' )

This is achieved by below SORT
Code:

//SYSIN     DD *                                       
  SORT FIELDS=(4,36,CH,A,164,36,CH,A)                 
  OUTFIL FILES=01,INCLUDE=(1,2,CH,EQ,C'01')           
  OUTFIL FILES=02,                                     
  INCLUDE=(829,2,CH,EQ,C'D2'),                         
        OUTREC=(1:1,351,352:C'010000000',361:361,490) 
  OUTFIL FILES=03,                                     
  INCLUDE=(829,2,CH,EQ,C'I0',AND,3,1,CH,EQ,C'C'),     
        OUTREC=(1:1,351,352:C'020000000',361:361,490) 
  OUTFIL FILES=04,                                     
  INCLUDE=(829,2,CH,EQ,C'U1'),                         
        OUTREC=(1:1,351,352:C'030000000',361:361,490) 
  OUTFIL FILES=05,                                     
  INCLUDE=((829,2,CH,EQ,C'I0',AND,3,1,CH,EQ,C'D'),     
           AND,(248,4,CH,NE,C'ITFR',AND,               
                248,4,CH,NE,C'ETFR')),                 
        OUTREC=(1:1,351,352:C'040000000',361:361,490) 
  OUTFIL FILES=06,                                     
  INCLUDE=((829,2,CH,EQ,C'I0',AND,3,1,CH,EQ,C'D'),     
           AND,(248,4,CH,EQ,C'ITFR',OR,                 
                248,4,CH,EQ,C'ETFR')),                 
        OUTREC=(1:1,351,352:C'050000000',361:361,490)   
  OUTFIL FILES=07,INCLUDE=(1,2,CH,EQ,C'03')             
/*                                                     


Now I need to feed Seq Id 20, 40, 50 (File 3, 5, 6) as a single file to a program but sorted in Acct-Id and Tran-Id. If I concatenate since the files are split it will not be in Sorted order.

So can above Sort be made better so that condition for File 3,5,6 is met with correct Seq Id population but in a single file?





Thanks

arvibala,

Why are you splitting the files ? You can use IFTHEN statements on INREC to build the data and you can perform the sort later. Is your intention to modify the records and then sort keeping the header and trailer in place?

Files 2-6 are detailed records and I need to populate the sequence number on detailed records based on condition described above. I need to use only the detailed records to be processed in a program which has 3 inputs. File 2 is one input, File 4 is one input and Files 3, 5, 6 combined is one input and I have to sort again files 3, 5, 6. Can this be done in one single sort?

Arvibala,

Sort on what? A new key or same key as the original?

Just updating the values without splitting can be done as follows. You can use INREC if you want to sort on the newly added constants at pos 352.

I am just showing the updating of records based on your conditions. I added a include condition to filter unwanted records to be sorted.

Code:

//SYSIN    DD *                                                         
  INCLUDE COND=(001,2,SS,EQ,C'01,03',OR,                               
                829,2,SS,EQ,C'D2,U1',OR,                               
               (829,2,SS,EQ,C'I0',AND,3,1,SS,EQ,C'C,D'))               
                                                                       
  INREC IFTHEN=(WHEN=(829,2,CH,EQ,C'D2'),OVERLAY=(352:C'010000000')),   
  IFTHEN=(WHEN=(829,2,CH,EQ,C'U1'),OVERLAY=(352:C'030000000')),         
  IFTHEN=(WHEN=(829,2,CH,EQ,C'I0',AND,3,1,CH,EQ,C'C'),                 
       OVERLAY=(352:C'020000000')),                                     
  IFTHEN=(WHEN=(829,2,CH,EQ,C'I0',AND,3,1,CH,EQ,C'D'),                 
       OVERLAY=(352:C'040000000'),HIT=NEXT),                           
  IFTHEN=(WHEN=(829,2,CH,EQ,C'I0',AND,3,1,CH,EQ,C'D',AND,               
                248,4,SS,EQ,C'ITFR,ETFR'),OVERLAY=(352:C'050000000'))   
                                                                       
  SORT FIELDS=(4,36,CH,A,164,36,CH,A),EQUALS

Thanks Kolusu,

Quote:

I meant Sort in Same Key

I want Files 01, 02, 04, 07 as seperate files, as I have. Only 03, 05, 06 condition needs to be combined into a single file as that is related to 'I0'. Can this be done ?

Reason is one of the programs 3 inputs will be File 02, 04 and (03, 05, 06)

Thanks

arvibala,


Use FNAMES and give meaningful names to the output files.

H1 = header file
D2 = D2 record file
...

F356 will have all the records which are not included in any of the above outfiles.

Code:

//H1       DD SYSOUT=*     
//D2       DD SYSOUT=*     
//U1       DD SYSOUT=*     
//T1       DD SYSOUT=*     
//F356     DD SYSOUT=*     


Just add OUTFIL statements to the existing sort cards I gave after sort statement.
Code:

  OUTFIL FNAMES=H1,INCLUDE=(001,2,CH,EQ,C'01')   
  OUTFIL FNAMES=D2,INCLUDE=(829,2,CH,EQ,C'D2')   
  OUTFIL FNAMES=U1,INCLUDE=(829,2,CH,EQ,C'U1')   
  OUTFIL FNAMES=T1,INCLUDE=(001,2,CH,EQ,C'03')   
  OUTFIL FNAMES=F356,SAVE                         
//*
