1.2.5 V command
Function
Operation
Checks to confirm that data in a cassette tape file matches the original data in the
memory block from which it was saved.
When a V command
is
entered, the display
is
as
shown below.
*V
FILENAME:§
The monitor requests the operator
to
specify the file name
to
be verified.
For
example, when file "ABRACADABRA"
is
to
be verified, enter "ABRACADA-
BRA" from the ·keyboard
as
shown below. Note
that
the cassette tape must first
be rewound.
*V
FILENAME: ABRACADABRA
When the
I
CR
r key
is
pressed, verification
is
performed automatically. The
memory block with which the specified file
is
compared is indicated by informa-
tion recorded when
the
file was saved with the S command.
If
the
file name
is
not specified,
the
first cassette tape file data encountered will
be verified.
When the file data
is
the same
as
data in the memory block,
"OK"
is
displayed;
when it differs,
"ERROR"
is
displayed.
Although cassette deck read/write operation
is
highly reliable, it
is
recommended
that
a habit be made
of
verifying data every time a file
is
saved.
