IDading

RAID

The

disk

on

which

RAID

comes

contains

the

program

which

is

designed

to

be

used

in

56K

systans

only

whose

screen

rrerrory

is

located

at

add~ss

FOOOH.

To

load

RAID,

first

get

into

the

CP/M

cc:mmand

exealtive,

as

indicated

by

the

pranpt.

Load

the

RAID

diskette

in

type:

J

<REIURN>

The

filenane

is

cptional.,

If

typed,

it

can

include

a

drive

designator

and a

filetype

extension,

usin;

the

standard

CP/M

format.

I t

causes

the

selected

unambiguous

file

to

be

loaded

from

disk

into

memory.

IMPORTANT:

if

the

filetype

is

.HEX,

then

RAID

will

first

convert

the

file

into

bincu:y

format,

and

then

load

it

at

the

load

address

of

the

file

specified

when

the

file

was

asserbled.

'Ibis

enables

you

to

assemble

and

debug

programs

that

run

at

any

location,

rather

than

OlOOH

as

is

nonral

for

CP/M.

If

the

filetype

is

anything

else,

the

RAID

assune

the

already

in

(having

passed

thrcugh

procedure)

am

in

in

aOH.

Addresses

greater

than

the

are

not

re<:ClTlItended

because

this

walld

cause

RAID

to

overlay

CP

1M

,

which

is

not

normally

desired.

However,

ym

may

overlay

sate

or

all

of

CP/M

if

the

target

program

does

not

use

the

overlayed

part

of

CP/M.

It

is

not

recommended

to

use

the

lower

part

of

the

TPA

(Transient

Program

Area)

tecause

this

is

the

usual

area

for

the

target

pro;:J:tam.

With

the

exception

of

the

HELP

screen,

the

bulk

of

the

RAID pt:03ram

will

load

from

the

specified

load

address

upwards.

The

HELP

screen

occupies

approximately

1440

bytes

fran

the

load

address

downwards. Thus

the

simulated

prcg:tam

nay

overlay

the

help

area

in

nerory

and,

if

so,

the

help

screen

will

'not

be

displayed

when

the

help

camrand

is

input.

If

the

HELP

screen

data

has

been

disturbed

the

phrase

"HELP

SCREEN ID1' AVAIIABLE"

will

be

displayed

in

the

Rev.
