Not exactly. We have a built-in function, "_", which returns the value of last displayed expression. (See the detailed explanation at http://www.singular.uni-kl.de/Manual/2-0-5/sing_35.htm).
However, we do not recommend to use it while changing rings due to the reason that polynomial-based objects in Singular are ring-dependent.

We can illustrate it with the following code
Code:
ring r=0,(x,y),dp;
poly f=x2-y3;
groebner(jacob(f));
ideal T=_;
T;

Hi everybody.

Does any one knows how to make singular remember the values that was calculated before. I mean, there exist command like the "memoize" from Macaulay2?

the memoize command makes the procedure remember the results it had obtained before.

Thanks for any help.
