SYSTEM
Notation
and
Abbreviations
For
the
sake of
clarity
and
brevity,
we've
used
some
special
notation
and
type
styles
in this
book,
capitals and punctuation
indicate material
which must
be entered exactly
as
it
appears.
(The
only
punctuation
symbols
not entered are ellipses,
explained below.) For example,
in
the
line:
DUMP
LISTER (START
=
70O0,END
=
7100,TRA
=
7004)
every
letter
and
character should be typed as indicated.
lowercase
italics
represent
words,
letters,
characters or values
you
supply
from
a set
of acceptable
values
for a particular
command.
For example,
the
line:
LIST filename
indicates that
you can supply any
valid
file
specification
after list.
Ellipsis indicates that the
preceding items can be repeated.
For example:
ATTRIB
filename
(option,
.
. .)
indicates that
several options
may
be repeated
inside the parentheses.
b
This special
symbol
is
used occasionally
to indicate a
blank-space character
(ASCII code 32
decimal,
20
hexadecimal).
PRINT
"BHbltt!"
X'nnnn
Indicates that
nnnn
is
a
hexadecimal number.
All
other
numbers
in
the text
of
this
book
are
in
decimal form,
unless
otherwise
noted.
X'7000'
indicates the
hexadecimal value
7000
(decimal
28672).
COMPUTER TYPE
Any
words,
letters,
or
numbers
that are
displayed
on
the
screen
will
be
in
computer
type (dot-matrix).
Uppercase
letters
are used;
however, your
screen
at
times
may
display lowercase
letters
instead.
