Hello All,
   I am trying to write an arexx script that will read a scene file, memorize the
objects of the file, and their corresponding key frames. The program will then
memorize the key frames as an "action". It will read a few other files with the same
objects but with different keyframes, and will also remember these as "actions".
0nce it has read 2 or three or 6 or 21 of these "action files", It will have built up
a vocabulary of "actions" for the specific group of objects. Next, within this program,it will ask for a list of actions in a chronological order. From this list, and the
memorized "action" key frames it will write a composite scene file. This file is just a
compilation of the same objects with groups of key frames shifted to fit
one after the other. Is this clear?

Example:
1) You set up a scene file with a complex Mech object.
   With a whole bunch of parented objects/lights all with different envelopes
2) Set up frames 1->60 to be one full walk cycle
   and save the scene as"mech_walk"
3) Clear all keys
4) Set up frames 1-> 30 so that the mech fires a missle;
    save the scene as"mech_missle"
5) Clear all keys
6) Set up frames 1-> 30 so that the mech raises its arms in victory;
   save the scene as"mech_victory"
7) Now you go out to a shell an run this program/script
   and have it read all the files you saved.
8) Now the script has a 3 word vocabulary of "walk, missle, victory"
9) Now you type in a list like;
   walk,walk,walk,walk,walk,missle,missle,walk,missle,
   walk,missle,missle,missle,missle,victory
10) the program does the calculations (actually only shifting keyframes around)
    and writes out a LW scenefile, which you load up and render. (or modify)

It sounds easy enough to me. Does anyone have any suggestions/comments?
 Has anyone done this kind of thing before?
 Would this be easier as a straight arexx script?
or maybe an arexx script for a text editor?
I just started with arexx so any help would be appreciated. :)
Also does anyone know the SCENE FILE F0RMAT, I need it.
TIA
