Procedure to change the name of the indeterminates of a polynomial ring P. The i-th indeterminate will be given the name of the i-th element of the sequence of strings s (for 1 <= i <= #s); the sequence may have length less than the number of indeterminates of P, in which case the remaining indeterminate names remain unchanged.

This procedure only changes the name used in printing the elements of P. It does not assign to identifiers corresponding to the strings the indeterminates in P; to do this, use an assignment statement, or use angle brackets when creating the field.

Note that since this is a procedure that modifies P, it is necessary to have a reference ~P to P in the call to this function.

Given a poynomial ring P, return the i-th indeterminate of P (as an element of P).
