Answer Posted / arthi
DCB=(RECFM=F,LRECL=80,BLKSIZE=800)
RECFM - to specify the record format
F-Fixed length record
V-Variable length record
FB-Fixed Block
VB-Variable Block
U-Undefined
for fixed length record the BLKSIZE is multiple of LRECL. For variable length records, BLKSIZE is multiple of (largest record+4)
