First n terms of polynomial

If I have a polynomial, f, with many terms, is there a function that returns another polynomial that is the first n terms f with respect to the term order. For example, say f has 25 terms, I'd like to define a new polynomial that is the first 10 terms of f with respect to a term order.

Assume you have defined your polynomial p in SINGULAR. Then you can define an intvec v of the positions of the terms in p (w.r.t. the ordering) you want to be returned, say

Then you can use

to get the sum of the terms 1,2,3,8 and 12 of p.

Thank you ederc, that is exactly what I needed.
