So, if its just data (floats, vectors up to 5 dimensions), I've got
some IO-Macros on my homepage designed for ease of use:

#declare Array=array[x][y] { ... }
Save_Array(Array,"filename.ext")

#declare Array=Load_Array("filename.ext");

As for filenames, you'd have to save them in strings, but my
system wasn't designed (and tested) for that. Concerning the
state-loading:
#if (frame_number=0)
 [Initial setup]
 Save_Array(Initial_Data,"somedata.tmp")
#else
 #declare Initial_Data=Load_Array("somedata.tmp")
#end

This way, the initial frame will calculate the new data into an
array, and every frame thereafter will load the data. This assumes
that your first frame is 0, not 1 (which you would have to change
in the if-statement).

To generate identifiers, it is possible to "parse" strings:
#declare String="#declare Variable="
Then write this to HD and #include the newly created file.
I'm not so sure if "#declare Variable=" works though, cause
I think that you'd have to define the part behind "=" inside
the include-file as well, but you might experiment with that
knowledge...

Hope this gets you going,
Tim
