The CICS preprocessor EXCI option enables you to specify that the program being compiled uses the external CICS interface
                  (EXCI) to call a CICS application. 
                  
 
            	 
            
               		
               CAUTION:
                
                  		  
                  A CICS 
                     			 EXCI call can only be executed in a service that is Container Managed. An EXCI call executed in an Application Managed generates
                     an abend: 
                     			 EXIA 
                     		  
                  
 
                  		
                 
               		
                
                  		   
                  			 
                  -  EXCI=YES
                     			 
                  
- The program uses the external CICS interface (EXCI) to call a CICS application 
                     			 
                  
-  EXCI=NO
                     			 
                  
- The program does not use the external CICS interface (EXCI) to call a CICS application. This is the default. 
                     			 
                  
For example, 
                  		  /CICSECM(EXCI=YES). 
                  		
               
 
               		
               Note: When you specify this option, do not check 
                  		  EXEC CICS on the 
                  		  Compile tab of the Build Settings dialog box.
