I agree that it would be ideal if the JZOS batch launcher was

it's absolutely necessary just to do stuff like:

Whether there should be a system wide TZ variable is another discussion
:-) I'm not sure there should be anything else in /etc/profile that is
required for every java batch job.
It's also unfortunate that the DD is called STDENV but is doesn't follow
the same conventions as BPXBATCH STDENV (I'm not sure which came first).
I have no argument with the facility to run a shell script, it's just
the *requirement* for a script, and mainly the need to customize it for
CLASSPATH that I object to. Java classpath can hard enough to figure out
without dealing with shell script for-do-done loops and the syntax
complexities of shell variables, braces, quotes, wildcard expansion etc.
I suspect it deters a lot of people from using Java on z/OS: they find
that script and think "Hmmm, maybe I'll try Rexx first".
What would be ideal: STDENV DD to set environment variables in exactly
the same way as BPXBATCH, and maybe something like SCRIPT DD for an
optional initialization script.
