On the SET command, more than four users were specified with the OUTPUT and NOTIFY keywords. The combination of users specified on the two keywords can be a maximum of four different users. In other words, the cumulative total of unique users may not exceed four in both the OUTPUT and NOTIFY keywords. The same four users may be specified on each keyword. However, if four users are specified on one of the keywords, a (different) fifth user may not be specified on the other keyword. For example, if four users are specified on the OUTPUT keyword, a fifth user may not be specified on the NOTIFY keyword.
