Thanks Kirk and Scott for the explanations and advice, but I have a question: How do I run BPXBATSL with a "non-login" shell? Whenever I try to run my simple shell script (using the STDPARM DD to submit a multiple-line, multiple command shell invocation with semicolons between commands) I get the abend that says "you can't run /bin/login with _BPX_SHAREAS=MUST".
I did review the Unix Commands manual under BPXBATCH (pp920 et. al. in the PDF) but did not see any instruction on how to run a "non-login" shell.

Peter, As others have said, the accounting for the OMVS processes is not aggregated into the job statistics of the original job. While BPXBATCH will run the shell in a separate OMVS address space, it is also possible to run the shell and your cp commands in the original JES address space. BPXBATSL will allow you to do this with a non-login shell. Our COZBATCH utility is a superior alternative, and allows you to run a login shell in the same address space while at the same time using inline shell input. For example, the following will run everything in the original JES2 address space: // EXEC PGM=COZBATCH //MYDD1 DISP=SHR,DSN=... //MYDD2 DISP=SHR,DSN=... //STDIN DD * # input to the z/OS Unix shell: cp //DD:MYDD1 /my/unix/file1 cp //DD:MYDD2 /my/unix/file2 // Note: access to the job step DDs by the cp commands demonstrates that they are running in the JES address space.
