Hai all,

I have a dataset with a single record in it with LRECL=80 and i use it as a header to concatinate to some other output file.PROJECT.TEST.HEADER is only 80 bytes and PROJECT.TEST.OUTFILE is 160 bytes.Now when i run this job,it fails due to DCB attributes mismatch as we cannot concatinate the two datasets as LRECL is different.If i delete the dataset PROJECT.TEST.HEADER and create a new dataset by name PROJECT.TEST.HEADER with LRECL=160 bytes the job runs fine and i am getting the desired output.Is there anyway where in we can change the existing's dataset LRECL from 80 bytes to 160 bytes without deleting it as my main concern is i do not want to delete the dataset and create a new one.Is it possible and how can my problem be solved and please correct me if i am wrong ?

Code:

//STEP0100 EXEC PGM=IEBGENER //SYSUT1   DD   DSN=PROJECT.TEST.HEADER,DISP=SHR //         DD   DSN=PROJECT.TEST.OUTFILE,DISP=SHR //SYSUT2   DD   DSN=PROJECT.TEST.OUT,DISP=(NEW,CATLG,CATLG), //              DCB=(LRECL=160,RECFM=FB,BLKSIZE=27840),UNIT=SYSDA //              SAPCE=(TRK,(1,1),RLSE)

PROJECT.TEST.HEADER(LRECL=80)

Code:

TODAY IS THURSDAY

PROJECT.TEST.OUTFILE(LRECL=160)

Code:

1 2 3 4 5

EXPECTED PROJECT.TEST.OUT

Code:

TODAY IS THURSDAY 1 2 3 4 5

mfuser,

If your shop has fileaid , then you can concatenate different Lrecl datasets. try this job.

Thanks Kolusu & Ravi ,

I have tried out all the three JCLS in my shop and i am acheiving my desired results correctly.
