You can start or stop the EZASOKET interface by issuing an EXEC CICS LINK to program EZACIC20. Make sure you include the following steps in the LINKing program: 
- Define the COMMAREA for EZACIC20. This can be done by including the EZACICA.CPY copybook in your program.
 
- Initialize the COMMAREA values as follows: 
| P20TYPE | 
 I Initialization 
T Immediate Termination 
D Deferred Termination 
 | 
| P20OBJ | 
 C CICS EZASOKET interface 
L Listener 
 | 
| P20LIST | 
 Name of listener if this is listener initialization/termination. 
 | 
 
 
 
- Issue the EXEC CICS LINK to program EZACIC20. 
Note: 
EZACIC20 will not return until the function is complete.
 
 
- Check the P20RET field for the response from EZACIC20. 
Note: 
 Note: If the EZASOKET interface is not in startup or termination and no COMMAREA was provided, the E20L user abend code is issued by EZACIC20.
