while creating GDG why we use SRCDSCB in DCB,
we can create without this but what is the specific functionality of this parameter

eg :

SORTOUT DD DISP=(NEW,CATLG,DELETE),
DCB=(SRCDSCB,RECFM=FB,LRECL=50,BLKSIZE=5000),
SPACE=(50,(&SPACE01),RLSE),AVGREC=K,

DFSMS is also known as SMS, Storage Management Subsystem, which the storage team configure to manage the storage environments.

If every dataset, DASD or tape is allocated a valid DATACLAS at creation time, then a GDS will no longer require to have a model DSCB in the DCB paramter in the JCL.
