The 11 graphics generated by the program are still available in the stack. If

you want to re-start the animation, simply use: 11 ANIMATE. (Function

ANIMATE is available by using „°L@)GROB L @ANIMA). The

animation will be re-started. Press $ to stop the animation once more.

Notice that the number 11 will still be listed in stack level 1. Press ƒ to

drop it from the stack.

Suppose that you want to keep the figures that compose this animation in a

variable. You can create a list of these figures, let’s call it WLIST, by using:

11 „°@)TYPE@ @

LIST ³ ~~wlist~ K

Press J to recover your list of variables. The variable @WLIST should now be

listed in your soft-menu keys. To re-animate this list of variables you could use

the following program:

« Start program

WLIST Place list WLIST in stack

OBJ Decompose list, stack level 1 = 11

ANIMATE Start animation

» End program

Save this program in a variable called RANIM (Re-ANIMate). To run it, press

@RANIM.

The following program will animate the graphics in WLIST forward and

backwards:

« Start program

WLIST DUP Place list WLIST in stack, make extra copy

REVLIST + Reverse order, concatenate 2 lists

OBJ Decompose list in elements, level 1 = 22

ANIMATE Start animation

» End program

Save this program in a variable called RANI2 (Re-ANImate version 2). To run

it, press @RANI2. The animation now simulates a ripple in the surface of
