You can run the same JCL jobstreams in MSS as you can on the mainframe. MSS checks the JCL statements for errors as far as possible. Several parameters, especially on DD statements, have no meaning in MSS running on Windows or UNIX and are ignored. This section describes the differences that apply when using JCL jobstreams in the MSS environment instead of the MVS mainframe environment.
MSS supports both MVS JCL and VSE JCL. The following sections describe the levels of support for MVS JCL and VSE JCL.
