ugBASIC User Manual

   POLYLINE { [x1] },{ [y1] } TO { [x2] },{ [x2] } { TO ... },{ [c] }
   POLYLINE { [x1] },{ [y1] } TO { [x2] },{ [x2] } { TO ... }
   POLYLINE TO { [x2] },{ [x2] } { TO ... },{ [c] }
   POLYLINE TO { [x2] },{ [x2] } { TO ... }

This instruction draws a polyline, that is a line formed by multiple lines, on the screen, starting from the coordinates (x1, y1) to arrive at the coordinates (xn, yn), using the color c. The start can be omitted: in this case, ugBASIC will draw starting from the last drawn position. If the color is omitted, the last color selected with the INK or PEN command will be used. Finally, the default line style is full but a 16 bit bitmask can be set with the SET LINE command.

  POLYLINE 10,10 TO 20,20 TO 20,30 TO 20,10, WHITE
