Re: [Closed REQ 5722]: Using gcl to move multiple objects simultaneously.

You'd asked (oops, a month ago!) whether there's a GCL command that moves
several objects at once.  In effect, there is: if you wrap a series of
GCL commands in a "(progn ... )" list, they'll all be executed before the
display is redrawn.  So you must still specify the transformations separately,
but you can make them seem to happen simultaneously.  For example:
   (progn
     (xform-set arm1  1 0 0 0  0 1 0 0  0 0 1 0  .5 .8 -1.2 1)
     (xform-set toe2  .866 -.5 0 0  .5 .866 0 0  0 0 1 0  1.5 2 0 1)
     (hdefine transform Telbow  ...)
   )
