The
analyzer
allows
you
to
create
a
special
program
le
called
A
UTOST
.
This
program
is
automatically
loaded
and
run
every
time
the
analyzer
is
turned
ON.
When
you
use
this
capability
,
the
disk
on
which
you
saved
A
UTOST
must
be
inserted
in
the
disk
drive
before
the
analyzer
is
turned
ON.
The
system
rst
checks
to
see
if
there
is
an
A
UTOREC
le
on
the
disk.
If
there
is
,
the
system
reads
the
A
UTOREC
le
to
set
up
the
analyzer
,
and
then
loads
and
runs
the
A
UTOST
program.
