These commands bring up and clear the two double high-res graphics screens that are available on the Laser 3000.

HGR5

HGR6

These commands bring up and clear two graphics screens that are special to the Laser 3000. See the graphics section for a full description.

DRAW HCIRCLE (x,y),radius[,aspect]

DRAW SCIRCLE (x,y),radius[,aspect]

These commands draw Hollow or Solid circles to the high resolution screen. Aspect can never be higher than 1, so if you need elongated shapes that are stretched vertically, only the double high-resolution modes can be used. These commands are stupid, because they'll start drawing a circle and give you an ?ILLEGAL QUANTITY ERROR as soon as an attempt at plotting off the screen border is made, making the commands almost useless. They are also quite slow.

DRAW HSQUARE (x1,y1 TO x2,y2)

DRAW SSQUARE (x1,y1 TO x2,y2)

These draw Hollow and Solid rectangles on the graphics screens, between the points described by x1,y1 and x2,y2.

PAINT (?????)

I assume this performs a fill. It'd be damn useful, if only I could figure out the syntax.
