               - From Online Express, click File > Field
                     		Mapping. The Field Mapping dialog box appears.
               
- To set the mapping direction, click Field Mappings
                  		> Mapping Direction and click One-way
                  		or Two-way. The default is Two-way.
               
- To create a mapping: 
                  		
                   
                     		  
                     - Place the mouse pointer over a screen field on the
                        			 Control list or a database or Working-Storage field on the
                        			 Field list.
                     
- Click and drag the mouse pointer from the field you selected in
                        			 step a to the field you want to map to on the other
                        			 list.
                     
- Release the mouse to complete the mapping. A one-sided or
                        			 double-sided arrow, depending on the mapping direction you selected, appears to
                        			 represent the mapping.
                     
 
Note:  
               	  
               	 
                
                  		
                  - When you have the mapping direction set to one-way, Online Express
                     		  creates an output from the field where the mapping originates and an input to
                     		  the field where the mapping terminates.
                  
- When you have the mapping direction set to two-way, Online Express
                     		  creates an input/output for each field.
                  
- You can also modify or delete Working-Storage fields, and do a
                     		  variety of other tasks from the Field Mapping dialog box.
