Auto Pan, Left Margin, Right Margin And Bottom Margin
Note: The “X increment” and “Y increment” parameters are used for manual
panning only. Auto panning relies on the values set in the “Left margin”,
“Right margin” and “Bottom margin” parameters.
“Auto Pan” is used to enable and disable auto panning. When it is enabled
(set to “Y”), the values set in the “Left Margin”, “Right Margin” and “Bottom
Margin” are used to determine the number of characters that will always be
visible to the left and right of the cursor and the number of lines that will always
be visible below the cursor. If the cursor moves beyond the value specified, the
entire contents of the screen are panned or shifted to comply with the values set in
the margin parameters.
Example: The value set in the “Left Margin” and “Right Margin” is 2. The
value set in the “Bottom Margin” is 3. This specifies that 2 characters must
always be displayed to the left and right of the cursor, and 3 lines must
always be displayed below the cursor (Bottom Margin).
The contents of the screen will not auto pan or shift until the cursor is
moved past the minimum specified in a margin parameter. If the cursor is
moved past the “Left Margin” setting, the screen pans to the right. If the
cursor moves past the “Right Margin” setting, the screen pans to the left.
If the cursor is moved beyond the “Bottom Margin” setting, the screen
contents pan up.
X Increment And Y Increment
Manual panning – shifting the contents of the screen using the <BLUE> key in
combination with the <LEFT>, <RIGHT>, <UP> and <DOWN> arrow keys –
relies on the values set in “X Increment” and “Y Increment” to determine the
number of columns (spaces) and rows (lines) to pan or shift.
“X Increment” determines the number of spaces the screen pans to the left or right
when the <BLUE> key is pressed followed by the <LEFT> or <RIGHT> arrow key.
“Y Increment” determines the number of lines the screen pans up or down when the
<BLUE> key is pressed followed by the <UP> or <DOWN> arrow key.
