The MAX function returns the content of the argument-1 that contains the maximum value. The type of this function depends
                  upon the argument types as follows: 
                  
 
            
             
               	 
                
                  	 
                  
                      
                        		   
                        		   
                        		  
                         
                           			 
                            
                              				
                              | Argument Type | Function Type |

                              | (some arguments can be integer) |  |

                  - If more than one argument-1 is specified, all arguments must be of the same class except alphabetic and alphanumeric arguments
                     which can be mixed. 
                     	 
                  
  
            
            
               Returned Values
 
               	  
                
                  	 
                  - The returned value is the content of the argument-1 having the greatest value. The comparisons used to determine the greatest
                     value are made according to the rules for relation conditions. See the topic 
                     		Relation Condition in the chapter 
                     		Procedure Division. 
                     	 
                  
- If more than one argument-1 has the same greatest value, the content of the argument-1 returned is the leftmost argument-1
                     having that value. 
                     	 
                  
- If the type of the function is alphanumeric 
                     		
                      
                        		   or national or national
 the size of the returned value is the same as the size of the selected argument-1. 
                        		
                      
- If the value of argument-1 is numeric non-integer, results are returned in floating-point format.
