The language allows the whole scene or individual figures can be translated and rotated. The figures can also be bent at any joint, thus allowing articulation. The whole scene, single figures, or individual ellipsoids can be scaled in size along each of the axes separately. Additionally an ellipsoid can be scaled in size thus moving all the other ellipsoids connected to it except for those connected through a nominated joint. The scene or a figure can be positioned so that the lowest point just touches the ground.
All variables are global.
The spacing of items is free, providing there is at least one space between items. Various levels of echoing and diagnostics can be produced. The frame numbers must be integers in the range 0 to 32767. The earliest frame number is assumed to be 0, and is notional only, and that frame is not drawn. Where more than one action occurs between a given pair of frames, they are performed in the order in which the respective commands are presented.
