This display interface uses BIOS call $10 functions for a fast
|
|
display interface. A couple of state variables is contained
|
|
in a vector that is task specific such that different tasks
|
|
may use different windows. For simplicity windows always
|
|
span the whole width of the screen. They can be defined by
|
|
top and bottom line. This mechanism is used for a convenient
|
|
status display line on the bottom of the screen.
