An external writer can select output from JES2 after JES2 builds the output group from the data sets. Your installation can supply its own writer routines or use the external writer processor supplied by IBM® by naming the writer as a subparameter of the SYSOUT= DD keyword. The operator then starts an external writer in a private address space, and the external writer writes the data using QSAM.

For details on the external writer, see The External Writer.
