The DUMMY parameter specifies that no device is to be
allocated to this DD statement and that no disposition
processing or I/O is to be
done.
One use of the DUMMY parameter is in testing a program.
When testing is finished and you want input or output
operations performed on the data set, replace the DD DUMMY
statement with a DD statement that fully defines the data
set.
