IMAGE SPECIFIER
[S(p)
(xl .m.zl
- Input/Output
the
number
of
Bytes
to/from
the
variable
string
starting
at
position
m and
ending
at
position
z,
with
parity
p (E=even,
O=odd,
none).
If
m, z and p are
omitted
the
entire
string
will
be output
as in the
string
variable$
as specified
by the
image
terminator
(x)
without
parity.
If
no terminator
is
used
then
the
string
will
end with
EOI.
[B(H/L)
(x),m,zl-
Input/Output
the
specified
H/L
number of Bytes
to or from
the
the
specified
integer
variable
array
starting
at
(m) array
location
and ending
at the
(z) position.
The data
transferred
will
not
change
the
the
other
half
of
the
16 bit
integer,
only
the
byte
specified
is changed
on
an ENTER command. There
is no change
to the data
with
the
OUTPUT
command.
[BL#,2,101
will
transfer
the
low
byte
of
position
2 thru
position
10 of the
integer
variable
array.
Note,
the
number
of
bytes
transferred
is
nine,
position
two
and
ten
are
included.
Transfer
termination
is
specified
by
the
image
terminator.
It
is the
user's
responsibility
to
insure
that
the array
size
and the
type
of array
are correct.
No check
is made on data
types.
The
values
of
m and z may be reversed
which
will
transfer
data
in the
reverse
order.
If
m and z
arethe
same then
only
one word
is transferred.
If mand z are omittedthenthe
integer
variable
is not considered
an array
and the
variable
is
transferred
with
or without
an EOI depending
on
the
image
terminator
(x).
[M(x).m,sl
- Input
/ Output
the
specified
number
of
16 bit
words
to / from
the
specified
integer
variable
(array)
starting
with
position
(m) and ending
with
position
(2).
The
number
of
words
transferred
is
defined
as
[z
-
m + 13.
Termination
is
specified
by
the
image
terminator.
It
is
the
user's
responsibility
to
insure
that
the array
size
and type
of array
are
correct.
No check
is
made on data
types.
The
values
of
m and z may be reversed
which
will
transfer
data
in the
reverse
order.
If
m and z
are the
same then
only
one word
istransferred.
Ifm and s are omitted
then
the
integer
variable
is not
considered
an array
and the
variable
is
transferredwith
or without
an EOI depending
on
the
image
terminator
(x).
