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
=
7000,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.
This special
symbol is used
occasionally
to indicate
a blank-space
character
(ASCII
code 32 decimal, 20
hexadecimal).
PRINT "DHBIB!"
X'nnnn"
Indicates
that nnnn is
a hexadecimal
number.
All
other
