      In
the following example, the addition operator (+) adds 100 to the
value of the CreditLimit field:
      
        r-addn.p
      
      
          
          
            
              | FOR EACH Customer:
  Customer.CreditLimit = Customer.CreditLimit + 100.
END. | 
          
        
Note
      
      Adding
two decimal expressions produces a DECIMAL value. Adding two INTEGER
expressions produces an INTEGER value. Adding an integer expression
(either INTEGER or INT64) and a decimal expression produces a DECIMAL
value. Adding an INTEGER and an INT64 expression produces an INT64
value.
