The CHAR-NATIONAL (national character) function returns a one-character value that is a character in the national program
                  collating sequence having the ordinal position equal to the value of the argument. 
                  
 
            
             
               	  
               	 
               The type of the function is national.

                  - Argument-1 must be an integer. 
                     	 
                  
  
                  	 
                  - The value of argument-1 must be greater than zero and less than or equal to the number of positions in the national program
                     collating sequence.

                  - The returned value is the character in the national program collating sequence having the ordinal position specifed by argument-1.
                     
                     	 
                  
  
                  	 
                  - If more than one character has the same ordinal positon in the current national program collating sequence, the returned value
                     is the first character defined for that position.
