Hi,

Is there a particular reason FILE-OPTIONS is a macro?

Should there be a FILE-OPTIONS-DIFFERENCE in addition to
FILE-OPTIONS-UNION?

The option "append" is described as

  writes are appended to existing contents

What happens if we then seek to the begining of the file and write?
Does it perform a seek to the end before every write as in POSIX,
or on some platforms may this simply start the output at the end
of the file?
