APPENDIX E: TEST

/DEMO

DISKETTE

HOW

TO

USE

The

"HOW

TO

USE"

programs provide

brief

descriptions

of

the other programs

on

the

Test/Demo

diskette.

THE

VIC-20 & C-64

WEDGES

Additional

commands

are available which allow you to type

short

instructions

to

the disk drive.

Load

and

run

the VIC-20

WEDGE

if

you have a VIC; use the C-64

WEDGE

if you have a

Commodore

64. Using either, you will be able

to

press backslash

(/)

followed by the

program

name

and

the

RETURN

key

to

load a program;

the

"/"

means load from disk drive.

For

example, type

"/how

to

use"

to

load

that

program.

Type

">"

or

"@"

and

then

press

RETURN

to

display

the

current disk

error

status.

Type">$"

or"@$"

and

RETURN

to

display the directory without erasing the current

program.

DOSS.1

The

DOS

5.

I

program

is

not

intended

to

be loaded directly,

but

is

loaded instead

from the program C-64

WEDGE.

Its load address

is

$CC00

hexadecimal.

PRINTER

TEST

The

PRINTER

TEST

prints a listing

of

characters in a form

that

makes it easy to

check the mechanical

and

electronic capabilities

of

the

printer.

DISK

ADDR

CHANGE

Use this

program

to

change the device number

of

the disk drive.

It

is

a soft

change-when

the system

is

turned off,

the

disk drive

is

reset

to

its original device

number.

VIEW BAM

The

VIEW BAM program allows a

programmer

to

examine

the

contents

of

the sec-

tors

that

make

up

the block availability

map

(BAM)-the

table

that

DOS uses

to

identify

blocks

that

have been allocated

to

the

files

on

that

diskette.

CHECK

DISK

The

CHECK

DISK

program

can be used

to

make sure a new diskette

that

has been

headered

is

in fact a good diskette.

The

program

writes

to

every block

to

verify its ability

to

store

information

and

identifies

any

diskette

that

contains a

bad

block.

Don't

use

such diskettes.

DISPLAYT&S

The

DISPLAY

T&S program allows a programmer

to

examine the contents

of

a

block by specifying the particular track

number

and

sector

number

that

identifies

that

block.

PERFORMANCE

TEST

The

PERFORMANCE

TEST

program

tests the electronic

and

mechanical capabili-

ties

of

the disk drive whenever necessary. Use this program whenever you suspect there

may be damage

to

the

drive.
