Frame Duration Keyword

<FrameDuration N>
<fd N>

    F parameter and % switch alternative.

    Used as a parameter this keyword sets the default frame duration (in ticks or retrace intervals), used in a frame this sets the duration of that frame (or more correctly, the time that the next frame is scheduled).  If you need to specify this in milliseconds please use the <MSFrameDuration> keyword.

    NOTE: This parameter (or <DefaultFrameDuration>) must be specified otherwise the default frame duration will be zero leading to some distinctly weird behavior.
