Answer / syam
The maximum number of DD statements per job step is 3273,
based on the number of single DD statements allowed for a
TIOT (task input output table) control block size of 64K.
This limit can be different depending on the
installation-defined TIOT size. The IBM-supplied default
TIOT size is 32K. For information about changing the size of
the TIOT, see ALLOCxx parmlib member section in z/OS MVS
Initialization and Tuning Reference. For information about
how dynamic allocation might cause changes to the task
input/output table (TIOT). see z/OS MVS Programming:
Authorized Assembler Services Guide.

Answer / raja
The maximum number of 255 steps can be there in a job. Each
step can have 3273 DD statements. From this statement we
can understand that in a single job we can have 255*3273 DD
