URSOR
The cursor operates by reversing the background and
foreground colours in the character position pointed to by
the active cursor position. The cursor is enabled using
TXT7.CURSOR ON. When active, the row the cursor
appears on is defined by TXT9.R<4:0> and the column is
defined by TXT10.C<5:0>. The position of the cursor can
be fixed using TXT9.CURSOR FREEZE.
CC:
The valid range for row is 0 to 15. The valid range for
column is 0 to 47. The cursor remains rectangular at all
times, it’s shape is not affected by italic attribute, therefore
it is not advised to use the cursor with italic characters.
TXT:
The valid range for row positioning is 0 to 24.
The valid range for column is 0 to 39.
19.3.15 S
PECIAL GRAPHICS CHARACTERS
CC/TXT:
Several special characters are provided for
improved OSD effects. These characters provide a choice
of 4 colours within a character cell. The total number of
special graphics characters is limited to 16.
They are stored in the character codes 8XH and 9XH of
the character table (32 ROM characters), or in the DRCs
which overlay character codes 8XH and 9XH. Each
special graphics character uses two consecutive normal
characters.
Fringing, underline and overline is not possible for special
graphics characters. Special graphics characters are
activated when TXT20.OSD PLANES = 1.
If the screen colour is transparent (implicit in mixed mode)
and inside the object the box attribute is set, then the
object is surrounded by video. If the box attribute is not set
the background colour inside the object will also be
displayed as transparent.
