The Scrolling Region command limits scrolling to a portion of the screen.
This feature is useful when one area of the screen must display immobile objects (such as touch
targets) while another area of the screen displays scrolling information.
A scrolling region is designated by specifying the top and bottom lines of the region. The
minimum size of a scrolling region is two lines. When specifying a scrolling region, the line
number of the top must be less than the line number of the bottom. (Lines on the TCS screen are
consecutively numbered from top to bottom.)
The scrolling region specifies which portion of the screen can scroll and the area within which
relative cursor movements are limited.
NOTE
Once inside the scrolling region, relative cursor commands cannot cause the cursor to leave the scrolling
region. Only the Move Cursor to Absolute Position command can move the cursor out of the scrolling
region (and then only when Origin Mode is reset). When the Origin Mode is set, the cursor can never leave
the scrolling region, even with a Move Cursor to Absolute Position command. See the discussion of the
Origin Mode command in this chapter.
If a scrolling region is specified while the Origin Mode is reset, the cursor moves to the home
position (column 1, line 1) of the screen. If a scrolling region is specified while the Origin Mode
is set, the cursor moves to the home position of the scrolling region (column I of the top line of
the scrolling region).
Normally, when a line scrolls out of a scrolling region, its characters disappear, its line type
reverts to normal, its character attributes are set to "off", and it reappears as the new line on the
other end of the scrolling region. However, if the NOCHANGE Attribute Mode is set, when a
line scrolls out of a scrolling region, only the characters disappear; the line type and character
attributes of the line remain unchanged when the line reappears (as a new line) at the other end of
the scrolling region. This allows character attributes and line types of each line within a scrolling
region to be preserved throughout scrolling operations.
