z/OS UNIX application environments

You can run your z/OS® UNIX System Services XL C/C++ application programs from the following environments:

z/OS shell
z/OS ISPF Shell (ISHELL)
TSO/E
To call an application program that resides in a z/OS UNIX file from the TSO/E READY prompt, you must use the BPXBATCH utility.
z/OS batch
To run an application program that resides in a z/OS UNIX file, you must use the BPXBATCH utility with the JCL EXEC statement.
z/OS shell through z/OS batch or TSO
By using the IBM-supplied BPXBATCH program, you can run an application program that resides in a z/OS UNIX file. You supply the name of the program as an argument to the BPXBATCH program, which invokes the shell environment. The BPXBATCH runs under the z/OS batch environment or under TSO.
