The RAID

display

A -

drawing

of

the

RAID

display

is

famd

at

the

beginning

of

this

manual,

for

reference

purposes.

It

occupies

the

top

18

lines

of

the

screen,

which

are

referred

to

as

the

"reserved"

portion.

This

display

will

always

l:e

on

the

screen

during

RAID

without

change.

The

only

exception

is

if

the

target

program

changes

the

screen

directly,

or

roves

the

cursor

into

the

reserved

part

of

the

screen.

If

the

target

program

simply

displays

its

·output

line-by-line

according

to

cursor

location,

using

the

normal

driver,

without

changing

the

cursor

location,

then

this

cutput

will

scroll

through

the

botton

six

lines

of

the

screen

only.

(This

is

a

feature

made

possible

by

Vector's

Extended

Systems

Monitor.)

In

order

to

make

effective

use

of

RAID,

it

is

not

wise

to

debug

programs

which

write

directly

to

the

reserved

part

of

the

screen.

Whenever

there

is

a

change

to

any

part·

of

the

system

whose

status

is

displayed

on

the

screen,

that

change

will

appear

i.rcnediately

on

the

screen.
