<h3>
Description:
</h3>
The Order command creates a new order and checks if the
polynomial which creates the order is
irreducible. Furthermore it calculates the real basis of the
new order. It is possible to change these defaults. The real
basis is only calculated if KASH_REAL_BASIS_CALC is not
equal 0. If KASH_ORDER_POLY_FACTOR is 0 the test of
irreducibility is omitted. In the case
KASH_ORDER_POLY_FACTOR equals 1 kash tests the polynomial
only in the case that the polynomial is given over Zx.

Example:
</h3>

<pre>

kash> KASHLEVEL("KASH_ORDER_POLY_FACTOR",2);
2
kash> O:=Order(x^2-1);
Error, polynomial is not irreducible
kash> KASHLEVEL("KASH_ORDER_POLY_FACTOR",0);
0
kash> O:=Order(x^2-1);
> Generating polynomial: x^2 - 1
