The 4.3bsd dbx has a misfeature in that it insists on an object file name
even if the user does not wish to supply one. It aborts when
no name is given:

% dbx
dbx version 3.22 of 5/1/87 13:51 (ethyl).
Type 'help' for help.
enter object file name (default is `a.out'): <--user hits return
dbx: fatal error: can't read a.out
% exit

Dbx can be useful without any object files. For example, it has a C expression
evaluator, so sometimes I use it as an interactive "expr" that can do floating
point arithmetic in infix notation. I have to give /bin/ed as a bogus file
name, when using the 4.3bsd dbx for doing calculations.

Fortunately, the SunOS 3.5 dbx does not have this problem. Kudos to Sun for
this!
