If you want only UNIX files to be checked for program control, and do not want programs loaded from MVS™ libraries to be checked, you can set up BPX.DAEMON.HFSCTL. However, doing this weakens some of the security provided by the BPX.DAEMON resource. It should be done only in restricted and carefully considered cases, or if you do not already run with BPX.DAEMON but want to gain only a subset of the benefits of running with BPX.DAEMON.
