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 on= e would be helpful here. >=20 > That does feel like the wrong default; even GNU dc doesn't do that, a= nd > the principle of least surprise would suggest exiting is the right > thing to do.

Interesting observation - I've got to admit that I hardly ever use dc (despite being the owner of a collection of HP UPN calculators ;-) ). Ironically, I couldn't wrap my head around HP RPN calculators in the '90s, = so I used a TI-85 or TI-89 instead. Now, I do all my non-trivial math using = RPN in `dc'. :-) -Ravi I'll forward this to the author of this bc/dc and I'm sure he will offer a patched version (unless there are strong reasons for the current behavior, e.g. compatibility with another dc ...)
