is a decimal number specifying the relative column to which you
wish to move the cursor. A positive number specifies how many
columns to the right you wish to move the cursor; a negative num-
ber specifies how many columns to the left.
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:
