Which documentations describes the SH concatenation for other than instream? Also, where in the documentation does it say that it inserts whitespace after each record?
The treatment of semicolons is bog standard, but it wouldn't hurt to spell it out. -- Shmuel (Seymour J.)

What BPXBATCH does is look at the leading "SH" in it's PARM and then pass the rest of the string as the argument to "/bin/sh -c" STDPARM washes away the record boundaries (see the doc). The semicolons are required at the end of DD:STDPARM records so that this single argument to "/bin/sh -c " can be broken into multiple shell commands. The whole thing is an ugly hack. FWIW, I've been using the shell in z/OS batch since 2007 with its stdin coming from //STDIN DD *. And yes, I know what here documents are. I just don't use brain dead BPXBATCH.
