of

the

screen.

Each

of

lines

stxJw

one

The

first

two

lines

show

the

two

instructions

most

recently

simulated.

They

are

not

necessarily

consecutive

in

nem:n:y,

because'they

may

be

jumps,

calls,

returns,

etc.

The

third

line,

the

highlighted

one, shows

the

instruction

abalt

to

be

simulated.

The

last

four

lines

show

the

four

instructions

following

the

current

instruction

in

memory.

They

may

or

may

not

be

the

next

instructions

to

be

simulated.

Each

line

gives

the
