Create the algebraic closure A of the field K.
Currently K may be Q, a finite field or a rational function
field over a finite field or the rational field.
Create the algebraic closure A of the rational field Q.
(Procedure.)
Given an algebraically closed field A and a string S, reassign
the string prefix of the names of A to be S. By default, this
prefix is "r". When new variables are introduced by
root taking, they are named by this prefix with the number appended
(see A.i below).
