I=E2=80=99ve got a function in the Brain-Dead SHell=E2=84=A2 that I=E2=80=
=99m writing for
homework that looks like this:
	Biobuf in;

	void bdsh(int f) {
		Binit(&in, f, OREAD); yyparse(); Bterm(&in);
	}
This function gets called for each file named in argv[] after main()
open(2)s it.

My question is: is the call Bterm necessary, or will Binit
reinitialize the global Biobuf correctly on its own=E2=80=94or am I court=
ing
trouble some other way?  The man page for bio(2) is a bit vauge on
reusing Biobufs.
