Display Control
When using the above escape sequences, the data visible on the screen always remains
unchanged.
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.
If you specify a column number greater than the right boundary of the screen, the cursor will
move to the right boundary. If you specify a row number greater than the last displayed row,
the cursor will move to the last displayed row.
Example: The window contains 24 rows. The following escape sequence moves the cursor to
the 20th column of the 7th row on the screen:
Ec&a6y19C
Workspace Addressing
You can specify the location of any character within the active workspace by supplying
workspace-relative row and column coordinates. (This function is disabled when Memory
Lock mode is on.) To move the cursor to another character position using workspace address-
ing, use any of the following escape sequences:
Ec&a <column number> c <row number>R
Ec&a <row number> r <column number>C
Ec&a <column number> C
Ec&a <row number>
R
where:
<column number>
<row number>
is a decimal number specifying the column coordinate (within dis-
play memory) of the character at which you want the cursor
positioned. Zero specifies the first (leftmost) column in the work-
space.
is a decimal number specifying the row coordinate (within display
memory) of the character at which you want the cursor positioned.
Zero specifies the first (top) row in the workspace.
When using the above escape sequences, the data visible in the window 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.
