The VERIFY command is provided so that you can instruct DOS to verify all
disk write accesses have been performed successfully.  The command format is
as follows:

       VERIFY [ON | OFF]

The verify state remains unchanged until another VERIFY command is entered
or the system is restarted.  The normal (default) verify state is OFF.  If the
command is entered without parameters DOS displays the current verify state
and leaves it unchanged.

Verification may be enabled on a command by command basis using COPY with
the /V option (see the help file COPY for details).

Setting the verify state to ON causes all subsequent disk write operations to
take longer than normal.  This may not be too objectionable if you have a fixed
disk but may be a source of real irritation in a one or two floppy system.
