This

command

causes

the

target

program

to

execute

indepeOOently

of

RAID,

beginning

at

the

set

value

of

the

pc.

It

is

not

a

simulation,

but

a

real

execution,

in

real

time.

You may

include

up

to

six

optional

break-point

addresses.

When

execution

of

the

target

program

reaches

one

of

these

addresses,

execution

will

stop

and

control

will

return

to

'RAID.

This

is

accomplished

by

replacing

the

opcodes

at

the

specified

addresses

with

FF

restart

codes.

Execute

Directly

and

return

(LF)

This

camrarx1

is

exeOlted

directly

fran

the

keyboard

using

the.

(LF)

key.

It

will

cause

the

target

pco3t:am

to

execute

directly,

in

real

time,

any

called

routine.

This

is

particularly

useful

for

disk

access

or

print

rc:utines

which

cannot

l::e

simulated

in

RAID.

'Ibis

c:x:mmarxl

causes

the

real

time

execution

of

the

called

subroutine

to

halt

at

the

next

memory

location

past

the

calling

instruction

when

the

subroutine

returns.

This

is

of

particular

value

when

debugging

a

program

which

calls

routines

which

have

already

been

debugged.

Because,

of

the

limitation

of

not

l::eing

able

to

set

break

points,

this

conunand

will

not
