AmigaBASIC to QB64pe question out of left field

Each AREA statement defines exactly one corner point of the polygon and you don't return to the startpoint, that's implied to close the polygon.

Then optional a PATTERN statement can define a fill pattern and finally AREAFILL triggers filling of the polygon and by that resets the entire AREA point sequence.
