ENTER
A

lets
you
know when
it
is
ready
to
accept
a new command
by
sending
you
the
message:
READY
The
ACCOUNT.
EDIT,
OPERATOR,
OUTPUT
and
TEST
commands
have
subcommands.
After
entering
one
of
these
commands
the
system
lets
you
know
it
is
ready
to
accept
a subcommand
by
sending
you
the
name
of
the
cQmmand.
For
example,
in
the
following
sequence
you
enter
the
OPERATOR
command
after
receiving
a
READY
message.
The
system
then
sends
you
the
OPERATOR
message
indicating
that
you
can
enter
any
of
the
subcommands
of
the
OPERATOR
command:
READY
operator
OPERATOR
If
instead
of
entering
a subcommand
you
want
to
enter
a command,
enter
the
END
subcommand
to
make
the
READY
message
appear
again.
The
system
remains
able
to
receive
commands
until
you
enter
one
of
the
five
commands
that
have
subcommands.
The
system
then
accepts
only
that
command's
subcommands
until
you
request
a
READY
message
by
entering
the
END
subcommand.

uppercase
letters.
