Copy KSDS file to another with different record lengths

36_5_7.gif

Requirement: I need to copy some records from one VSAM KSDS file into another KSDS file, where the filenames are accepted as a parameter to a cobol program.



I tried to do this by calling REPRO utility using IDCAMS, in which I specified the INDATASET and OUTDATASET as the two KSDS files respectively.

I suceeded in the following cases.


    1. When Record Length of INDATASET and OUTDATASET are identical.
    2. When Record Length of INDATASET is lesser than the OUTDATASET.

Now I need to do the following. When I tried, I got an Abend icon_cry.gif .


    1. When Record Length of INDATASET is greater than the OUTDATASET.


icon_question.gif How can I do this using REPRO ?
icon_question.gif Is there any way, other than IDCAMS - REPRO ?


Regards,
Sinu Sam

Hi,
Using sort, you can copy the VSAM file (with greater record length) into a flat file. Use the following code snippet. The outrec parameter in the sort card gives the length to be copied from the input. I have also used some sort conditions.


Code:

//STEP010  EXEC PGM=SORT,REGION=6400K             
//SORTIN   DD DSN=VSAM FILE,                 
//         DISP=SHR                                   
//SORTOUT  DD DSN=FLAT FILE,               
//            DISP=(NEW,CATLG,DELETE),               
//            UNIT=SYSDA,                             
//            SPACE=(CYL,(2,10),RLSE),               
//            DCB=(LRECL=80,BLKSIZE=8000,RECFM=FB)   
//SYSIN    DD *                                       
       SORT FIELDS=(1,10,CH,A)                       
       INCLUDE COND=(9,1,CH,EQ,C'A',OR,9,1,CH,EQ,C'B')
       OUTREC FIELDS=(1:1,80)

Could you explain this, i couldn't get u here.

Also, Rajdeep's JCL creates a 'flat file' but u need a KSDS (of smaller LRECL). So u create a KSDS cluster of smaller LRECL using IDCAMS/File-Aid and then use REPRO to copy FLAT-FILE to the newly created cluster.



Thanks,
Asif
