You can invoke BPXBATCH under TSO/E like this:

BPXBATCH SH|PGM program_name [arg1...argN]

where:

• When SH is specified, program_name is the name of a shell command or a file containing a shell script. SH starts a login shell which processes your .profile before running a shell command or shell script. SH is the default; therefore, you can allocate a file containing a shell script to the STDIN ddname, invoke BPXBATCH without any parameters, and the shell script will be invoked.
• When PGM is specified, program_name is the name of an executable file that is stored in a z/OS UNIX file. Inadvertent use of a shell script with PGM may result in a process that will not end as expected, and will require use of the kill -9 pid command to force termination.
• You can supply optional arguments, arg1...argN, to program_name.
• You can invoke BPXBATCH without any parameters on the command line and, instead, place the parameter data in a file or data set defined by STDPARM.

Prior to invoking BPXBATCH, you can allocate any of the resources discussed previously, using the TSO/E ALLOCATE command with the following ddnames:
