Hi,

I've the following query / suggestion.

Is it possible to limit the amount of caching that mma does?

For example:

factorial[n_] := factorial [n] = n * factorial[n-1]
factorial[0] = 1;

With factorial[5], there are five numbers held in memory.

In larger recursions this chews up memory quite fast.
A useful feature would be to be able to limit mma to holding the last 'x'
numbers in memory.
Is it possible to implement such a feature, or would it have to be built in
by Wolfram?

Any responses appreciated.

Regards
Mark
