.MF.l'-DRY

The

memory

block

from

ADRI

through

ADR2

is

filled

with

the

byte

"DATA".

This

is

useful

for

setting

memory

to

Zero.

The end

of

a

file

or

assembled

program

will

stand

out

more

clearly

if

memory

is

first

zeroed.

For

test

purposes,

single

instructions

can

be

executed

continuously

so

that

bus

waveforms

are

more

easily

interpreted.

This

is

done

by

filling

a

block

of

memory

with

a

repeated

instruction

sequence

wi

th

a jump

to

the

start

of

the

block

so

that

the

program

loops

continuously.
