Function: Call Sortn

 Function: Call Sortn

Purpose: To sort the values of its numeric argument in ascending order.

Syntax:  CALL SORTN(<of> Vaar-1 <,  ... Var-n>)

              Var-n  is a numeric variable. If you use a variable list in the form VAR1-Varn,                              precede  the list with the word "of".

              Arguments to the CALL SORTN routine cannot be constants. You may use  array                    references as   arguments to this routine as well (see the following examples)

  Examples
For these examples, x1=8, x2=2, x3=., x4=1, a=9, b=7, c=8.

Also, an array is defined as array nums[4] x1-x4;

     Call Routine                                          Returns
CALL SORTN(of x1-x4)                        x1=., x2=1, x3=2, x4=8
CALL SORTN(of nums[*])                        x1=., x2=1, x3=2, x4=8
CALL SORTN(a,b,c)                                 a=7, b=8, c=9
 
Program to grade quizzes, dropping the two lowest quiz
