string program_name(object obj)
Returns the name of the program of <obj>, resp. the name of the

replaces its programs with the efun replace_program().
As a special case, if <ob> is passed as 0, the function will
The name always ends in '.c'. It starts with a '/' unless the
driver is running in COMPAT mode.
CAVEAT: This efun swaps in the program if it is swapped out.
o = clone_object("/std/thing");
write(program_name(o)); --> writes "/std/thing.c" in !compat mode
and "std/thing.c" in compat mode
