// DD DUMMY
is the minimum coding -- additional parameters may be necessary.

Warning from the JCL Reference manual:
12.1.6.7 Do Not Concatenate Data Sets after a DUMMY Data Set


If you define a data set using the DUMMY parameter, do not concatenate other data sets after it. When the processing program asks to read a dummy data set, the system takes an end-of-data set exit immediately and ignores any data set that might be concatenated after the dummy.

Suggest you educate yourself by looking all these things up in the JCL manual and user guide BEFORE posting.
The problem I have is that people can explain things quickly but I can only comprehend slowly.
