is
a decimal
number
specifying
the
relative
row to
which
you wish
to
move
the
cursor. A positive
number
specifies how
many
rows
downward
you wish to move
the
cursor; a
negative
number
speci-
fies how
many
rows upward.
When
using
the
((R"
parameter
for row selection,
the
data
will (if necessary) be rolled
up
or
down to position
the
cursor
at
the
specified
data
character.
The
cursor
and
data
movement
will occur
as
follows:
•
If
the
specified coordinate lies
within
the
boundaries
of
the
window,
the
cursor
moves to
that
position
and
the
data
on
the
screen
remains
unchanged.
•
If
the
specified column is less
than
the
left
boundary
of
the
window,
the
cursor
moves
to
the
leftmost
column
in
the
window.
•
If
the
specified column exceeds
the
right
boundary
of
the
window,
the
cursor
moves to
the
rightmost
column
in
the
window.
• If,
when
using
the
((R"
parameter
for row selection,
the
specified cursor-relative row pre-
cedes
the
top
line
of
the
window
currently
visible on
the
screen,
the
cursor
moves to
the
specified column
in
the
top row of
the
window
and
the
text
rolls
downward
until
the
specified row
appears
in
the
top
line
of
the
window.
• If,
when
using
the
((R"
parameter
for row selection,
the
specified cursor-relative row follows
the
bottom
line
currently
visible on
the
screen,
the
cursor moves to
the
specified column
in
the
bottom
row
of
the
window
and
the
text
rolls
upward
until
the
specified row
appears
in
the
bottom
line
of
the
window.
• If,
when
using
the
((Y"
parameter
for row selection,
the
selected row is
greater
than
the
last
displayed row,
the
cursor
will move to
the
last
displayed row.
If
you specify only a column number,
the
cursor
remains
in
the
current
row. Similarly,
if
you
specify only a row number,
the
cursor
remains
in
the
current
column.
Example:
The
following escape sequence moves
the
cursor
(and
rolls
the
text
if
necessary) so
that
it
is
positioned
at
the
character
residing
15 columns
to
the
right
and
25 rows
above
the
current
cursor
position
in
the
active workspace:
