Display Control
•
If
the
specified column coordinate exceeds
the
right
boundary
of
the
window,
the
cursor
moves to
the
rightmost
column
in
the
window.
•
If
the
absolute row coordinate is less
than
that
of
the
top line
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
the
absolute row coordinate exceeds
that
of
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
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.
NOTE:
If
you specify a row
greater
than
the
last
workspace row, lines will be discarded from
the
top of
the
workspace to create
as
many
lines
as
necessary,
at
the
bottom
of
the
workspace, to locate
the
cursor
in
the
specified line.
Example:
The
active workspace contains 119 rows.
The
following escape sequence moves
the
cursor (and rolls
the
text
ifneccessary) so
that
it
is positioned
at
the
character
residing
in
the
60th
column of
the
87th
row
in
the
workspace:
Ec&a86r59C
Cursor-Relative Addressing
You
can specify
the
location of
any
character
within
the
active workspace by supplying row
and
column coordinates
that
are
relative to
the
current
cursor position (this function is
disabled for rows selected
with
the
parmeter
cCR",
see below,
when
Memory Lock mode is on).
To
move
the
cursor
to
another
character
position using cursor-relative addressing,
use
any
of
the
following escape sequences:
Ec&a
+/-
<column
number>c
+/-
<row
number>R
Ec&a
+/-
<column
number>c
+/-
<row
number>Y
Ec&a
+/-
<row
number>r
+/-
<column
number>C
Ec&a
+/-
<row
number>y
+/-
<column
number>C
Ec&a
+/-
<column
number>C
Ec&a
+/-
<row
number>R
Ec&a
+/-
<row
number>Y
