The keywords associated with the DCB parameter are LRECL,
RECFM, BLKSIZE and DSORG.
Ex://step1 DD DSN=dataset,
DISP=(NEW,CATLG,DELETE),
UNIT=unitname,
SPACE=(CYL,(30,30),RLSE),
DCB=(MODEL,RECFM=FB,LRECL=100,BLKSIZE=0)
The sysem looks for DCB information in the program code
first. DCB can be coded in DD statement
