VERIFY
VERIFY
[switch]
Internal

~
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.
