FABS3662I BLKSIZE OR LRECL OF SORTOUT4 FILE IS ’0’; MAX ALLOWABLE SIZE FOR DEVICE IS USED

Explanation
 Either BLKSIZE or LRECL is not specified on the SORTOUT4 DD statement.

System action
 PSSR continues processing, using the maximum
record size for the device assigned to the SORTOUT4 DD statement as
BLKSIZE. It uses BLKSIZE minus 4 as LRECL.

User response
 If the program ends because of an IMS or MVS error, code both LRECL and BLKSIZE on the DD statement and rerun the job.
Otherwise, none.
Tip: For some DASD devices (such as 3375 or 3380), the default block size and record
length result in wasted space. If the maximum record size for the device is considerably smaller
than the maximum track length, it is desirable to code BLKSIZE and LRECL on the DD statement.
