Yes. As I said, ".bas", and quoted the Wiki entry pointing out
that you shouldn't forbid users to not use ".bas" and shouldn't
assume a file's format in input purely on it's name or type.

Which is why the documentation specifies that it assumes that the
BASIC program has not got any extra byte information appended
after the final terminator. If you want to examine those sorts of
files, you must use a different method.
 
Just as if I had said: this method works of positive numbers, and
somebody responds: but it doesn't work for negative numbers. Yes,
I know, which is why I said that it works for positive numbers!
