When this variable is set to 1 (on, true, yes), on a fatal error, the runtime will send its shutdown error message to the UNIX syslog daemon, console, or Windows event log. The runtime uses the same logic as the C$SYSLOG routine. (See C$SYSLOG in Appendix I for more information). The error message also includes the name of the runtime error file so that the administrator can view it for more information. The default value for this variable is 0 (off, false, no).
