The Enter Account Number operation exposes the account number of the record to be retrieved. It automatically sets the request
               type to display information. 
               	 
            
 
            	 
             
               		
               - Click 
                  		  Operation > 
                  		  New. 
                  		
               
- In the 
                  		  Operation Name field, type 
                  		  Enter Account Number. 
                  		
               
- From the 
                  		  Active Screen drop-down list, click 
                  		  ACCTSET.ACCTMNU. This is the name of the main menu of the ACCT application. 
                  		
               
- Leave the default value, 
                  		  ANY SCREEN, in the 
                  		  Previous Screen field. 
                  		
               
- Leave the 
                  		  Transaction ID field blank. This operation does not start a transaction. 
                  		
               
- Leave 
                  		  Create Default Mappings unchecked. 
                  		
               
- Click 
                  		  OK. This returns you to the 
                  		  Interface Mapper and shows the CICS Screen ACCTSET.ACCTMNU. 
                  		  
                  We're now ready to map our interface fields and make some assignments for this operation. As we learned from running this
                     application in its original form, we need to provide the application with a D (for display) in the REQUEST TYPE field and
                     an account number in the ACCOUNT field in order to retrieve information about an account. We will start with specifying the
                     input field for the account number. 
                     		  
                   
- On the 
                  		  CICS Screen pane, locate the 
                  		  ACCTM field by hovering over the entry fields. ACCTM is located to the right of the ACCOUNT label. It is the field where users
                  enter the account number. 
                  		
               
- Click and drag the ACCTM field to the 
                  		  Interface Fields pane and drop it there. 
                  		  
                  The name ACCTM is not particularly descriptive. Because this field is really the input field for the account number, we will
                     rename it in the 
                     			 Interface Mapper so that it is more recognizable. The name we use here will appear as the field label in our generated Windows Forms client.
                     
                     		  
                   
- In the 
                  		  Interface Fields pane, double-click 
                  		  ACCTM. 
                  		
               
- In the 
                  		  Name field, type 
                  		  AccountNumber. The other fields on this dialog box are accurate so no additional adjusting is necessary here. 
                  		
               
- Click 
                  		  OK. 
                  		  
                  Notice that the 
                     			 Mappings pane shows the interface field with its new name, AccountNumber, mapping to the COBOL field ACCTM. 
                     		  
                   Now we will make some assignments that automatically set the value for the request to D for display, and set the attention
                     identifier. 
                     		  
                   
- On the 
                  		  CICS Screen pane, hover over the input field next to the REQUEST TYPE label. Note that the name of the input field is 
                  		  REQM. 
                  		
               
- In the 
                  		  Assignments pane, right-click and select 
                  		  New Assignment from the popup menu. 
                  		
               
- From the 
                  		  Assign to drop-down list, click 
                  		  REQM. 
                  		
               
- In the 
                  		  Field 1/Operand 1 field, type 
                  		  D, which is the value that tells the application to display information. 
                  		
               
- Click 
                  		  OK. 
                  		
               
- In the 
                  		  Assignments pane, right-click and select 
                  		  New Assignment from the popup menu. 
                  		
               
- From the 
                  		  Assign to drop-down list, click 
                  		  ATTENTION ID. This is the field that defines which AID key (for example, 
                  		  Enter, 
                  		  PF8, etc.) should be used. 
                  		
               
- From the 
                  		  Field 1/Operand 1 drop-down list, click 
                  		  ENTER. 
                  		
               
- Click 
                  		  OK.

                  		  File > Save CICSScreenWS.svi to save the completed Enter Account Number operation.
