By default, all text windows scroll automatically when filled with text. How-
ever, they can be made to not scroll, but start overwriting at the upper left cor-
ner instead. The keyword
SCRLOCK controls this feature.
Text and Cursor Attributes
Text can have any combination of 2 attributes besides normal: inverse and
blinking. The keyword
SETATTR sets the attribute for all subsequent print-
ing to the display.
The cursor can be in one of three states: hidden, underline, or full height. The
keyword
SETCURSOR establishes the cursor type. Also, the cursor can be
moved to any location within the current window by the
POSXY
keyword.
The keyword
GETWINDOW
loads the current window status, including at-
tribute and cursor information, into an array. ItÕs counterpart, PUTWIN-
DOW
, will immediately implement a windowÕs scaling, attribute, and cursor
location. Figure 23-15 creates two windows with differing attributes, then
switches between them as it prints what you type.
