A READ_EMCONTROLS request allows you to retrieve control information about your registered interest in a designated sublist within the list structure that you are monitoring. The sublist is identified by list number (LISTNUM) and entry key (ENTRYKEY). The information is returned in the answer area (ANSAREA).

You can issue a READ_EMCONTROLS request only for keyed list structures allocated in a coupling facility of CFLEVEL=3 or higher. READ_EMCONTROLS requests issued for a list structure allocated in a coupling facility of CFLEVEL=0, 1, or 2 will fail.
