A sample graphics program

Here follows a simple example to draw a line on the graphics screen.

Drawing a straight line

The program below draws a straight line from the point (50, 200) to another (300, 200).

GCLEAR ! Initializes the graphics screen.

MOVE 50,200 ! Moves the pen to the point (50, 200).

DRAW 300,200 ! Draws a straight line to the point (300, 200).

END

Drawing a circle

Here follows an example of sub-program for drawing a circle. Giving coordinates of the

center and a radius to this sub-programs as arguments allows you to draw a circle.

Changing the start value and the end value of the parameter Theta in this sub-program

allows you to draw a circular arc too.

SUB Drawcircle(Centx,Centy,R) !

DEG ! Uses "°" has the unit of agnle.

X=Centx+R !

Y=Centy !

MOVE X,Y ! Moves the pen to the start point.

For Theta=1 to 360 !

X=INT(COS(Theta)*R+Centx) ! Calculates the x coordinate of a

point on the circle

Y=INT(SIN(Theta)*R+Centy) ! Calculates the y coordinate of a

point on the circle.

DRAW X,Y ! Draws a line to the point (X, Y)

NEXT Theta !

SUBEND !
