      The calculator uses Reverse Polish Notation. To use RPN, it is        
      necessary to enter the two numbers to be operated on and then enter   
      the operation  (+ - * ). The  + - * /  keys enter numbers into the   
      calculator entry register and add, subtract, multiply or divide the   
      numbers that are in the entry register and the result register.       
      For example:

                       +     5    30.00 (The number 5 is still stored  
                       -     5    25.00 in the entry register and may  
                       *     5   125.00 be used without entering it    
                       /     5    25.00  for each calculation.)        
                                     
      Calculation  results may be inserted  into documents  by pressing the 
      "Insert Result"  softkey.  Spaces, tabs, and carriage returns may be  
      inserted into the document while the calculator is displayed.         
                                                                            
      When exiting the calculator function, the calculator register and     
      memory values are saved for the next calculator session.                            
                                                                            
      The '<' and '>' keys perform a binary shift left and shift right.
