sort a list
Syntax 

Sort(V:LIST):NULL

where V is a variable containing a list.

Description
This function sorts the elements of the list in V with respect to the default comparisons related to their types; it overwrites V and returns NULL.

For more on the default comparisons, see Relational Operators in the chapter on operators. For more complicated sorting, see SortBy , SortedBy .

Example 
  L := [3,2,1];
  Sort(L);  -- this returns nothing and modifies L
  L;
[1, 2, 3]
-------------------------------
  Use R ::= QQ[x,y,z];
  L := [x,y,z];
  Sort(L);  -- this returns nothing and modifies L
  L[1];
z
-------------------------------
  Sort([y,x,z,x^2]);  -- this returns nothing!!
  Sorted([y,x,x^2]);  -- this returns the sorted list
[y, x, x^2]
