The following example assumes that no scratch or garbage
files exist on the source diskette.
Then,
the reorganization
process requires
a
minimum amount
or
operato~
interaction:

It should be noted
tha~
no file selection commands were used.
The
resulting
destination
diskette
will contain all files
from the source diskette,
but they may be in diTferent places
on
the
·sur-Face
of
the
diskette.
Thus, a reorganization
process cannot be followed with a
veriTication
process
Tor
the
same diskette pair.
The
"N"
option could have been used
in the above example to suppress the
printing
of
the
file
names as they were being copied.
The
last
example
shows
the rile append process.
The
example assumes that there is an MOOS diskette
in
drive
1.
Alio,
it
a~sumes
that the diskette in drive zero has a Tamily
of files which are to be copied to the destination
diskette.
The Tamily has file names which start with the letters
"FOR".
