IBM Health Checker for z/OS User's Guide
SC23-6843-02
Unless specifying REMOTE=YES and REXX=NO, this macro must be invoked
from an exit routine associated with the HZSADDCHECK dynamic exit.
Otherwise, it must be invoked from the remote check routine task.
The check routine and the message table must be in an APF-authorized
library.
The caller should include the HZSZCONS macro to get equate symbols
for the return and reason codes.
