the
Cursor
Using
an
Escape Sequence
An
escape sequence
can
also
be
used
to
move
the
cursor (known
as
"addressing"
the
cursor)
to any
location
on the
current page
or to
another page.
Moving
on the
Current
Page
Either
of two
methods
may be
used
to
move
the
cursor
on the
current page.
One
method
uses
an
ASCII conversion
of the
(decimal) number
of the row or
column;
the
other uses
the
number
itself.
Using
an
ASCII Conversion
(Not
recommended
if
line length
is
132
columns)
To
position
the
cursor
to a new row and
column, enter
the
sequence

c
%
where
r
denotes
the
desired
row (in
ASCII) (see Appendix

c
denotes
the
desired column
(in
ASCII) (see Appendix

100.
Using
the
Decimal Number
To
position
the
cursor regardless
of
whether
line
width
is 80 or 132
columns,
enter
the
sequence
ESC.9rrRcccC
where

the
number
of the
desired
row
(HOME
=

ccc
denotes
the
number
of the

(HOM
E =
