:animate fra,del,rep
This command is only available for WIMS OEF and doc, and MUST appear on the first line. 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.
:animstep n
Set up an integer which can be called in any evaluation. Used for animation. Direct use of this command must be avoided under WIMS.
