Chapter 6 / Command Reference
VERIFY
VERIFY
[switch]
Internal
,
i
~
J
Turns
the
verify' switch
on
or
off,
or displays the current setting
of VERIFY. VERIFY has the same purpose as the
IV
switch
in
the
COpy
command. When
it
is
on,
it
tells MS-DOS to verify
that
the
data
written to disk can be read without error.
Parameters
switch
can
be
ON
or OFF.
ON/OFF remain
in
effect until a program executes a SET VER-
IFY system call or until
you
use the VERIFY command again.
When VERIFY is
on,
it
verifies all writes to disk.
If
you omit all parameters, MS-DOS
returns
the current setting
of VERIFY.
Notes
and
Suggestions
• By keeping VERIFY
on,
you
always know
that
data
written
to
disk
can
be
read
back. Note, however,
that
this
slows
operation.
