In this example, the FIELDNO function is used to determine which field that a variable, which contains a field number, points to in a record. This example requires that you create the following variables.

Variable name	DataType	Subtype
CurrentFieldNo	Integer	Not applicable
CustomerRec	Record	Customer

CASE CurrentFieldNo OF  
  Customer.FIELDNO("No."):   
    ...  
  Customer.FIELDNO(Name):   
    ...  
  Customer.FIELDNO(Address):  
    ...  
  ELSE  
    ...  
END;  

This construct allows you to take actions based on the field number contained in the CurrentFieldNo variable.
