Hi there,
I have to create a report output file, but I have to make sure my output file is no bigger than 30 MB. Please kindly advise if I could do this in JCL or any other solutions in COBOL?
Thanks in advance!

Hi,
Here is the sample for defininig the data set.
DISP=(,CATLG,CATLG),
UNIT=XXXX,
SPACE=(CYL,(X,Y),RLSE),
DCB=(RECFM=FB,LRECL=80)
You need to change the XXXX and X,Y as per your requirement.
Thanks

Hi, Krishy,
Thanks, I know how to define the output data set, but I don't know how to fill in the XXXX, X, Y to make sure my output is no bigger than 30 MB
DISP=(,CATLG,CATLG),
UNIT=XXXX,
SPACE=(CYL,(X,Y),RLSE),
DCB=(RECFM=FB,LRECL=80)

use the AVGREC=U DD statement parameter in conjunction with the SPACE= parameter
| Code: |
DSN=a.b.c,
DISP=(NEW,CATLG,DELETE),
UNIT=SYSDA,
AVGREC=U,SPACE=(80,(375000),RLSE),
DCB=(RECFM=FB,LRECL=80)
|
primary allocation is 30,000,000/80
the actual required space to store this dataset will exceed 30M as devices vary in their optimal blocking factors, but this method will allow for 30M data. |

for gdg
| Code: |
DSN=a.b.c(+1),
DISP=(NEW,CATLG,DELETE),
UNIT=SYSDA,
AVGREC=U,SPACE=(80,(375000),RLSE),
DCB=(RECFM=FB,LRECL=80)

Have a good day!!
