          Application No. 08/724,568                                                  


               Claims 1 and 13 are illustrative of the claimed                        
          invention, and they read as follows:                                        
                    1.  In a selective call unit that receives a                      
               sequence of interspersed message fragments transmitted by              
               a messaging system, a method for optimizing memory                     
               utilization of the selective call unit, the method                     
               comprising in the selective call unit the steps of:                    
                    receiving a message length command from the                       
               messaging system indicating a total message length of a                
               message, said message including a plurality of                         
               interspersed message fragments, pending transmission from              
               the messaging system;                                                  
                    determining whether there is sufficient memory                    
               available in the selective call unit according to the                  
               message length command;                                                
                    reserving memory space equivalent to the total                    
               message length for receiving the message when the total                
               message length is equal to or less than available memory               
               space; and                                                             
                    disallowing reception of the message when the total               
               message length is greater than available memory space.                 
               13.  In a messaging system having a transmitter for                    
               transmitting to a selective call unit a sequence of                    
               interspersed message fragments, a method for optimizing                
               memory utilization of the selective call unit, the method              
               comprising in the messaging system the steps of:                       
                    receiving a plurality of messages from at least one               
               caller communicating with the messaging system, the                    
               plurality of messages pending transmission to the                      
               selective call unit;                                                   
                    determining a plurality of message length commands                
               each indicative of a message length of a corresponding                 
                                          3
