So, you're building a file with the data retrieved? Maybe just retrieve it
to a temp file name and then change the name when you have it completely
downloaded. CL program can then check for the real name to see if it
exists, if it does then you know the download completed fully.

Not ideal, but should work.

For the specific (and simple) case of checking whether the data
transfer completed successfully, I think this is the cleanest
approach. It is actually close to ideal. It's sort of analogous to
performing database operations that don't "count for real" until an
explicit commit.

This is simpler and more direct than futzing with an exit code. The
exit code is most appropriate if you have a few different kinds of
failures (or possibly successes) that you want to distinguish among.
The exit code is meant to serve the same role as the "end code" (or
"ending code") that you see in the completion message of a native i
job.

(Jim, I get the feeling you already know all this, but maybe some
other readers don't.)
