Right. BPXBATCH starts a new address space which inherits none of the DDs.
BPXBATSL runs in the job step address space, but has onerous APF entanglements.
I don't know that BPXWUNIX is better.
The cumbersome alternative is to use Rexx; BPXWDYN('alloc dd(FW) ...'), then
address SYSCALL spawn with BPX_SHAREAS=MUST. Details are left as an
exercise for the student. The MVS-OE forum might be helpful.
