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. 
  
 
	 
		 
		  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.
