What are the keywords associated with DCB? How can you
specify DCB information? What is the OS precedence for
obtaining that DCB information, ie. where does the system
look for it first?
Answer Posted / pradeep salian
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
