To use the CodeWatch ON-unit triggering notification feature, set the following environment variable in the configuration for the enterprise server you are using for debugging with CodeWatch. 
	 
 
	 MFPLI_CONFIG_DIR=<directory> 
		: The read/write location where to create the 
		
CWNOTIF.DAT file that allows CodeWatch and the PL/I run time to communicate. This is typically the root directory of the current enterprise server instance that you are using. 
		
Note: This variable is set automatically using the value in the 
		  
PL/I Configuration Directory field on the General tab of the Enterprise Server Administrator (). You can use either that value or the root directory of the current enterprise server instance.
