You can create any number of data sets in one use of IEBDG. You must code a separate DD statement for each data set or member you are creating. The data sets or members must be new.

If you are creating a new member of a partitioned data set or PDSE, the DD statement must refer to that specific member. Do this by coding the data set name parameter as DSNAME=datasetname(membername).

You can also create sequential data sets. If the data set is sequential, it can be basic format, large format, extended format, compressed format, a UNIX file, a TSO terminal or on tape. If you identify the same sequential data set for input and output in one operation, the utility might destroy some input data before it is read. This might cause I/O errors. They can be the same member of a partitioned data set because the utility writes the member in a different area of the data set. The data set maximum block size cannot exceed 32760 bytes.
