Auto
camnands
An
auto
command
is
a
CCP
canmand
that
is
executed
automatically
when
CP/M
is
booted
up.
You
have
the
choice
of
making
the
canmand
take
place
either
upon
a
cold
boot,
a warm
boot,
or
both.
As
an
example
of
an
auto
carnnand,
normally
you
have
to
type
MEASIC
(return)
after
the
CCP
prompt
A>
in
order
to
get
Microsoft
BASIC
running
(assuming
there
is
an
MEASIC
on
the
system
disk.)
With
the
auto
canmand
"MEASIC
(return)"
you
can
cause
the
system
to
boot
directly
into
Microsoft
BASIC,
byPassing
the
CP/M
executive.
Further,
Microsoft
BASIC
will
automatically
load
and
execute
an
application
program
if
the
name
of
the
program
appears
after
the
"MEASIC."
Thus,
you
can
create
a
very
impressive
turn-key
applications
system,
which
goes
directly
to
a
user
menu,
by
creating
the
auto
canmand
"MEASIC
XXXXX
(return)",
where
XXXXX
is
the
name
of
the
applications
program.
In
this
way,
the
user
never
interacts
with
either
the
CP/M
or
the
BASIC
executives.
'The
auto
canrnand
is
stored
on
a
Vector
Graphic
CP/M
2.x
System
Disk.
You
can
only
have
one
auto
canmand
per
disk.
This
one
auto
canmand
is
the
auto
canmand
which
is
executed
automatically
when you
boot
up
CP/M
2.x
from
THAT
disk.
Of
course,
a
system
disk
does
not
have
to
have
any
auto
canmand.
It
is
optional.
'The

none

it
is

Save
configuration
selections
You
have
the
choice
of
making
your
configuration
selections
temporary
-
resident
only
in
memory
but
not
on
disk
-
or
saving
them
permanently
on
a
Personalized
CP/M
System
Disk.
Clearly,
in
order
to
have
an
auto
canmand
which
takes
effect
in
response
to
a
COLD
boot,
the
auto
command
must
be
stored
on
a
disk.
Thus,
if
you
are
creating
a
cold
boot
auto
command
in
the
configuration
procedure,
you
MUST
take
the
option
of
saving
the
configuration
selections
on
disk.
The
follCMing
is
the
configuration
procedure:
1)
Mount
the
:Personalized
Vector
Graphic
CP/M
2.x
System
Disk,
the
one
you
want
to
configure,
in
drive
A,
if
not
already
there.
2)
Make
sure
CCP
is
in
control.
If
not,
return
control
to
the
Extended
Systems
Monitor
executive
and
cold
boot
from
the
disk
in
drive
A.
If
CCP
is
in
control,
then
do
a warm
boot
by
depressing
control-C.
3)
FollCMing
the
CP/M
executive
prompt
A>,
type
CONFIG
(return).

will
