Yeah I saw that. Maybe I should look one more time at that option.

Yes. But I'm not sure L3P supports 0 CLEAR... But that's an issue to look at later. I guess I'll have to make (at least)
two output options. For the moment, I use 0 CLEAR, but it is possible that it is dead end. Even though the Master .DAT
file is one of the most elementary of the files, I believe it's not too difficult to change it's look or even to split
it up or make a batch file calling L3P NFrames times of it.

It must, and it will. In POV, I think it's done by post-processing the POV file. Or maybe it's possible to set some
command line parameters to the L3P call.
The compulsary static Scene* object will have variable Position and Matrix properties.
*) Previously referred to as World.
I have put together a little demo. It does nothing at all but just illustrates how the different files may look. No
files will actually be written, they will all just appear as edit windows.
http://home.swipnet.se/simlego/ldraw/lda2001.zip
To the upper left is the source file. I think it will be the only file visible for the user while writing the script.
At lower left: Master .DAT file.
At upper right: Scene file for the latest frame shot, called on from the Master file and calling any child objects "next
of kin".
Middle right: Latest child object file for latest frame.
Lower right: Should be the "RAM", with all object's current properties. (But not all properties are shown on this demo.)
Due to the size of the edit windows, some text in some windows will likely disappear at the top of its window. If you
wish to see it, just click on it and press PgUp.
Changes in any other edit window except the upper left will be lost when clicking on Compile.
Try it out. LMKWYT. (I think it will take lots of work...)
