The value is given in terms of a 1024x1024 plotter window. Note that C 'TM3' can be negative to make the amount of time after the last C title frame less than that between title frames. In this example, all the X-coordinates are set to 512, and the C horizontal centering is always set to 1, so each line of text will C be centered horizontally. When the color index is omitted, the C assumed value is that of the internal parameter 'FGC'. C C IYST specifies the Y-coordinate that will be at the vertical center C of the frame when scrolling begins.
