Ah ok that made more sense. So SPANIM 11,"XY+",-1000,500,0 means to "display sprite 11, and within 1000/60 sec, move it 500 pixels right and 0 pixels up, endless loop". The + means it's RELATIVE to the current coordinates. Without + it'll mean "display sprite 11, within 1000/60 sec, move it to coordinate (500,0) endless loop." In SmileBasic, coordinate (500,0) is the upper right corner.
