Have the first value written in your file indicate whether this is the
data has been already generated... might even work <g>

Try #if (clock=initial_clock) ...

Yeah I did try that but it still would not work in some of the ways I
wanted.

However I have now cracked the problem using another method.

Thanks for the suggestion though.

Dave.

Actually #if (frame_number=initial_frame)... works slightly better than my
previous way.  Slight question: what is wrong with the other/this method?

There is nothing wrong with your methods at all.

Its just to get round the problem I set up 2 scene files.

An initial scene (for setting all of my initial particle parameters etc)

An the main scene (which the animation ini file calls)

I have just found it easier doing it this way.

Dave
