But then I = noticed the "DC_EXPR_EXIT" envvar, which restores the desired behavior. = That lead me to discover "DC_ENV_ARGS" and, correspondingly, = "BC_ENV_ARGS"; that last one would be helpful here. That does feel like the wrong default; even GNU dc doesn't do that, and the principle of least surprise would suggest exiting is the right thing to do. It's also unlikely you want to evaluate something and then use it interactively. Jess
