This command is only available for WIMS OEF and doc, and MUST appear on the first line or after the command alt. Set up animation for fra frames, with del seconds between frames, and rep repetitions (rep=0 means infinite repetition).<br> Frame control is done via two variables: <tt>animstep</tt> (integer) going from 1 to frame count, and <tt>s</tt> going from 0 to 1.
