Here are some results for DOS 7.1 (or whatever the DOS that comes with Windows
'98 SE is called):

Using fchmod to change a file from read-write to read-only seems to work, as
long as you don't write to the file after the fchmod call. If you write after
fchmod(..., S_IRUSR), then the file reverts to read-write. I will add a note
to the fchmod info page.

It seems that DOS does not have the same separation between open attributes
and file attributes that Windows '98 SE (and '95 & ME?) does. I'm guessing
that this is a consequence of the magical LFN API.

Bye, Rich =]
