the shell (when dbx exits) ?

Thanks,

You can't. The exit status is returned to the parent, or to
init if the parent dies first; the child gets inherited by init
in this case.

Besides that, I don't think that dbx allows you specify an exit value
in any event. Why would you need to accomplish this?

I am doing some automated testing under dbx control. So from a shell
script I am invoking dbx and executing the target program. I rely on
the exit code feature to determine whether the test passed or failed.
So only if dbx exits with the exit code of the target program, I can
verify it from the shell. I know gdb allows an exit value to be
mentioned with the quit command. Is there any way that I can
acccomplish my requirement with dbx (including the plugin options)?

get your prog to write its exit code to a file, then read it from your
dbx shell script

Or put a breakpoint in exit(); once you hit it print ($r3).
