When x = 16, any shape that is drawn will be displayed with a
rotation of 90°. The variable x may assume a value between
0-255. The number used to calculate the rotation is x modulo 64.
DRAW
The syntax of the DRAW command is as follows:
DRAW
n AT x,y
n is the number of the shape to be drawn. x,y is the coordinate on
which the shape is to be centered. DRAW will plot the shape
using the previously chosen rotation , scaling , and color (ROT,
SCALE , and HCOLOR respectively). If ORA W is used without
specifying a coordinate, the shape will be drawn at the la st
location that was plotted to.
XDRAW
The XDRAW command allows the erasing of a previously dis-
played shape. XDRA W will not change any of the background
graphics. The syntax of this command is very similar to that of the
DRAW command .
