The System
Monitor

To store data
in
consecutive
memory
locations,
type
the
address
followed
by a
colon
and
the
data.
Each
data
item
should
be
separated
with
a
blank
space. The
monitor
can accept
as
many
data values
as
it
can
fit
on
a
command
line
(255
characters).
The
monitor
stores
the
address
after
the
last changed address
as
the
opened
address.
Therefore,
to
continue
entering
consecu-
tive
data values,
just
type
a
colon
followed
by
the
remainder
of
the data.

OF
Changing Registers
When
the
monitor
executes any
program
using
the
GO
com-
mand (described later),
it
first loads
the
6502's registers
with
the
values
in
locations
45
through
49.
To alter these values, first
execute a register examine.
*CTRL-E
A=OF
X=FC
Y=07
P=
BO
S=11
Then,
type
a
colon
followed
by
the
new
values.
*:

*CTRL-E
A=01
X=02
Y=03
P=04
S=OS
This
command
sequence
works
because
the
examine
register
command
stored
45
as
the
opened
address.

Data
Suppose
that
the
data
which
is
to
be stored
in
one
memory
block
already exists
in
another
memory
block
. The act
of
reading
that
data
followed
by
re-entering
it
would
involve
wasted
effort
