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

!) Function:   UPCASE Purpose:   To  change all letters to uppercase.                                                  NOTE: The corresponding fuction LOWCASE changes uppercase to lowcase Syntax : UPCASE(character-value)                                 character-value is any SAS character value.             If a length has not been previously assigned, the length of the resulting             variable will be the length of the argument Example: ***Primary function: UPCASE ***Other function: DIM; data mixed;   length a b c d e $ 1 ;   input a b c d e x y;   datalines ;   M f P p D 1 2   m f m F M 3 4 ; run ;   data upper;   set mixed;   array all_c[*] _character_;   do i = 1 to dim(all_c);     all_c[i] = upcase(all_c[i]);   end ;   drop i; run ; title 'Listing of Data Set UPPER' ; proc print data =upper noobs ; run ; Output Explanation Remember that uppercase and lowercase values are represented by different internal codes, so if

Function :MDY

 For the situations where you  only have month, day , and year values but do not have a SAS Date, the MDY functon can create a SAS date value, given the value for the month, day , and year .Kindly find a detailed example on how this is made possible in SAS Purpose:   To create a SAS Date from the month, day and year. Sytax: MDY(month, day, year)               month is a numeric variable or constant representing the month of the year (a number               from 1 to 12 ).               day   is a numeric variable or constant representing  the day of the month (a number                  from 1 to 31 ).               year  is a numeric variable or constant representing the year. Values of the month, day and time that do not define a valid date result in a missing value and an error message is written  to the SAS log.            Examples For these examples, M = 11 , D = 15 , Y = 2003.   Function                                              Returns          MDY(M,D,Y)
