1 = vertical graph split mode
1 = small font writes to buffer
0 = small font writes to display
1 = allows draws to use column 95 and
row 0
1 = draw to graph buffer only

Comments
Sets the interrupt handler to update
the run indicator, but not to process
APD, blink the cursor, or scan for
keys. It is useful when executing
I/O link port operations for speed.
Use when writing small font
characters. Determines if the
character will be written to the
display or to the corresponding
location in the graph backup buffer,
plotSScreen. Useful for building a
screen in RAM and then displaying
it in its entirety at once.
Causes all of the graph line and
point routines (pixel coordinates as
inputs) to be drawn to the graph
backup buffer instead of to the
display.
Enables the normal font to be
drawn using the small font
coordinate system. See section on
Display in the System Routine
Documentation.
Allows an application to have the
small font routines display a font
defined by an application. See
section on Display in the System
Routine Documentation.
Causes the GetKey routine to
recognize lower case alpha key
presses. When set, the key
sequence ƒƒcauses
lower case alpha mode to be set.
