Answer Posted / sush
PS IS THE NONVSAM DATASET AND ESDS IS THE VSAM DATASET.
LRECL IS THE LENGTH OF THE RECORDS IN PS OR PDS.
WHERE AS THE BLOCK SIZE IS THE AMOUNT OF VOLUME WHIH THE
JOB CAN OCCUPY ON THE DASD.
SYNTAX FOR DCB=(TRK,(PRIMARY,SECONDARY,BLOCK
SIZE),RLSSE,ROUND)
IN DCB PARAMETER FOR PS WE DONT GIVE DIRECTORY BLOCK SIZE
AS WE CANNOT ADD MEMBER IN PS WHERE AS IN PDS IT IS
MANDATORY AS IT DEFINES THE NO NUMBER OF MEMBERS THAT CAN
BE ADDED IN THE PDS BY FORMULA (6*N)-1 WHERE N= NO IN
DIRECTORY BLOCK FIELD
