Reply with quote

Hi,

This may look redundant but could find the relevant post .

Input file - PS, FB, LRECL=100
Input file:

0DATETIMESTAMP
1ABDCDE.....
1EFGHIJK.....
1LMNOPQ.....
1RSTUVX.....
1YZABCD....
26 DATE

Header Record:
1 - '0' record type
2-9 - DATE
10-19 - TIMESTAMP

Detail Record:
1 - '1' record type
2-100 - Data

Trailer Record:
1 - '2' record type
2-10 - Count (right justified - no leading zeros)
11-18 - DATE

Need to:
1) Have RC=16 if no header OR trailer record
2) Have RC=16 if if the count in the trailer is incorrect (i.e it is not equal to total no. of records in the input file excluding the trailer record).

PS: Need to achieve this using SYNCSORT.

Any help would be much appreciated.

OK..Though I intended to achieve above requirement in single step..since no response..I am planning to do it in multiple steps:

i) Segregate input file into 3 files:
a) Header file - only having header - Later check if its empty then abend the job
b) Trailer file - only having trailer - Later check if its empty then abend the job
c) Detail file - for the actual data to be processed later.
Thus, requirement (1) can be achieved.

ii) For the requirement (2), I am taking a count of the input file(excluding trailer) in a new file. Then I am using JOINKEYS to compare the count in this file and the count in the Trailer file. If it is not equal, abend the job.
For this I am using the following sort-card:

Code:
//SORTJNF1 DD DSN=VS059U.INSIGHT.COUN1,DISP=SHR   
//SORTJNF2 DD DSN=VS059U.INSIGHT.TRLR,DISP=SHR   
//SORTOUT  DD DUMMY                               
//SYSIN    DD *                                   
 JOINKEYS FILES=F1,FIELDS=(1,10,A)               
 JOINKEYS FILES=F2,FIELDS=(1,10,A)               
 REFORMAT FIELDS=(F1:1,80,F2:1,80)               
 INCLUDE COND=(2,9,ZD,EQ,82,9,ZD)                 
 SORT FIELDS=COPY                                 
 OPTION NULLOUT=RC16           


Both JNF1 & JNF2 have LRECL=80, FB.

Here the problem is - the count in the trailer file is right justified (no leading zeros as mentioned earlier) while the count in my count file (SORTJNF1) is with leading zeros. So the job is abending.

SORTJNF1:

Code:
=COLS> ----+----1----+----2----+----3----+----4----+--
****** ***************************** Top of Data *****
000001 2000000009                                     
****** **************************** Bottom of Data ***
SORTJNF2:

Code:
 =COLS> ----+----1----+----2----+----3----+----4----
 ****** ***************************** Top of Data **
 000001 29        02172010                         
 ****** **************************** Bottom of Data   


Any suggestions..?

Vivek,

The below SyncSort job does what you asked for.
Code:
//STEP0100 EXEC PGM=SORT                                           
//SYSOUT   DD SYSOUT=*                                             
//SORTIN   DD DSN= Input File (FB/200)                             
//HDR      DD DUMMY                                                 
//TLR      DD DUMMY                                                 
//SYSIN    DD *                                                     
  OPTION COPY                                                       
  INREC IFTHEN=(WHEN=INIT,OVERLAY=(201:SEQNUM,9,ZD)),               
        IFTHEN=(WHEN=(1,1,ZD,EQ,2),                                 
                OVERLAY=(201:201,9,ZD,SUB,+2,M10,LENGTH=9))         
  OUTFIL FNAMES=HDR,INCLUDE=(1,1,CH,EQ,C'0'),NULLOFL=RC16           
  OUTFIL FNAMES=TLR,INCLUDE=(1,1,CH,EQ,C'2',AND,2,9,CH,EQ,201,9,CH),
                    NULLOFL=RC16

Thanks much Arun..!!!

Somehow this is ALMOST working but not fully. I think the count matching is causing the problem.

I ran the job using ur Sort card:

Code:
//SYSIN    DD *                                                       
  OPTION COPY                                                         
  INREC IFTHEN=(WHEN=INIT,OVERLAY=(81:SEQNUM,9,ZD)),                   
        IFTHEN=(WHEN=(1,1,ZD,EQ,2),                                   
                OVERLAY=(81:81,9,ZD,SUB,+2,M10,LENGTH=9))             
  OUTFIL FNAMES=HEADER,INCLUDE=(1,1,CH,EQ,C'0'),NULLOFL=RC16           
  OUTFIL FNAMES=DETAIL,INCLUDE=(1,1,CH,EQ,C'1')                       
  OUTFIL FNAMES=TRAILER,INCLUDE=(1,1,CH,EQ,C'2',AND,2,9,CH,EQ,81,9,CH),
                      NULLOFL=RC16

As I find, the include for TRAILER is working fine but the count is not matching.Consequently, the Trailer file is empty and the job is abending.

Arun, I dint get the purpose of "SUB,+2" in the sort card. I am not aquainted with this. Can you pls explain this?

NOTE: As mentioned earlier, count in the trailer in Input file is right justified (no leading zeros). Mask M10 will have leading blanks (bbbbbbbT). We dont have any mask (M0 to M25) which can have trailing blanks.

Hi Arun,

Here is why it is abending:

1)

Code:
INREC IFTHEN=(WHEN=INIT,OVERLAY=(81:SEQNUM,9,ZD)),                   
        IFTHEN=(WHEN=(1,1,ZD,EQ,2),                                   
                OVERLAY=(81:81,9,ZD,SUB,+2,M10,LENGTH=9))


above piece of sort card will count the records in the input (6 in this case) and then subtract 2 from it( to exclude header n trailer). So count will be 4 here.
But the correct count should be total no. of records(excluding trailer record). So we can resolve this by subtracting only 1.

2) Count in trailer is right justified while our count is left justified. So they will mismatch.

Pls correct me if I am wrong anywhere.

You're right. The sort job provided above assumes the actual count to be the total number of detail records. If you need the header also, you may replace the code to subtract +1 instead of +2.

I am not sure what you meant by this. Your initial post said "2-10 - Count (right justified - no leading zeros)", but the count in the sample input in your latest post is left justified. icon_rolleyes.gif

Oops..!! Actually, I am setting up the data and then was testing the sort card. Rightly pointed out. I have corrected the data now.

Still somehow, using the sortcard:

Code:
 OPTION COPY                                                         
 INREC IFTHEN=(WHEN=INIT,OVERLAY=(81:SEQNUM,9,ZD)),                   
       IFTHEN=(WHEN=(1,1,ZD,EQ,2),                                   
               OVERLAY=(81:81,9,ZD,SUB,+1,M10,LENGTH=9))             
 OUTFIL FNAMES=HEADER,INCLUDE=(1,1,CH,EQ,C'0'),NULLOFL=RC16           
 OUTFIL FNAMES=DETAIL,INCLUDE=(1,1,CH,EQ,C'1')                       
 OUTFIL FNAMES=TRAILER,INCLUDE=(1,1,CH,EQ,C'2',AND,2,9,CH,EQ,81,9,CH)
                                NULLOFL=RC16

What abend are you getting? Mention the abend code or post the abend messages. I tried executing the code above, but I am getting an RC=16
as expected. May be this has something to do with your site settings.

Vivek,

Is that abending with ABENDU0016 ???
Can you try executing the sort as below adding the parm.


Code:
STEP0100 EXEC PGM=SORT,PARM='NORC16'

My bad...this should not have gone this far...!!!
Actually was calling a customized proc in next step which would abend the job if RC>4.

Syam,
That parm "NORC16" is used when the default in one's system/installation for RC16 is ABE. Anyways, in my case its well set to NOABE. So need to do that. The trivial issue has stated above.

Much thanks Arun..!!! The job is working fine.
