Do
not
remove a
diskette
which contains a
file
opened
for
writing
(mode
=
O,
E,
or R). First close the
file.
This
is
because
the last
256
bytes
of data
may
not
have been
written
to
disk
yet.
Closing
the
file
will write the data,
if
it
hasn't
already
been
written.
Any
modification to
the resident
program (new,
editing,
load, merge,
etc.)
will
cause
open
files
to
be
closed.
