INTRODUCTION
-----------------------------------------------------------------------------

The simplest data type used by the TI-92 is the byte, followed by the word
and the long integer. However, it is useful to define more complex data
structures for more complex tasks. This text file describes some of the
data structures used by the TI-92.

This text file also describes some of the enumerated data types used by the
TI-92. These are integers in which predefined values have specific meanings.

ENUMERATED DATA TYPES
-----------------------------------------------------------------------------

color
-----
 0 = white on black
 1 = black on black (!!!)
 2 = white on black (??)
 3 = gray on white
 4 = black on white

font
----
 0 =  5(d) point font
 1 =  8(d) point font
 2 = 10(d) point font

DATA STRUCTURES
-----------------------------------------------------------------------------

point (4 bytes)
---------------
 00.W	x coordinate
 02.W	y coordinate

rect (8 bytes)
--------------
 00.W	x1 = coordinate of left edge
 02.W	y1 = coordinate of top edge
 04.W	x2 = coordinate of right edge
 06.W	y2 = coordinate of bottom edge

window (2A bytes)
-----------------
 00.W	flags
	03 = border width 0= 2 pts, 1 =1 pt
	05 = 0  store background
	     1  don't store background
	06 = translate LF, FF, and CR
	08 = draw border
	10 = similar to 11
	11 = check boundaries
	12 = display title
 02.B	(font) text font

 08.W	cursor x coordinate from window
 0A.W	cursor y coordinate from window

 10	(rect) border of window
 14	(rect) usable area of window
 18	(rect) border of window
 1C	(rect) inside of window (relative); top left = (0,0)
 20.W	handle of block where bitmap is stored
 26.L	pointer to window title
