XFERSYS UTILITY
ON TRSDOS 1.3
The Model
III
diskette
in this package
contains a NEW
version of TRSDOS which
is not compatible with
OLD
versions
of TRSDOS.
OLD TRSDOS diskettes
to be used
under
the NEW
TRSDOS
MUST
be XFERSYSed
before
use. Once
XFERSYSed,
an OLD TRSDOS
diskette becomes
a NEW TRSDOS
diskette
and
should
not
be
used with
OLD TRSDOS again.
If
you started
with
an OLD
system
or data diskette,
the
XFERSYSed
diskette
will be a
NEW
system or data diskette
respectively.
OLD diskettes
used under
NEW TRSDOS
without
XFERSYSing, may
cause
extraneous information
to
be
read
at
the
end of
files, giving
a false End-of-File
(EOF)
indication.
Some
programs
will not function
properly
under
these
conditions.
NEW diskettes used under OLD TRSDOS, may
not access
all
data and/or NEW programs may not run correctly.
If
you need to use the XFERSYS utility,
see the TRSDOS
section of your TRS-80 Model III
Disk System Owner's
Manual.
Note: When changing from one
TRSDOS to the other,
you MUST
press the RESET button each
time the
diskette in
Drive is changed.
You may also
XFERSYS onto a
NEW
data
disk. If this is done, all
system files of
the
system
diskette will be moved
onto the data
diskette.
