Internal usage

program code (program3/bsystem.p)

/*For each daemon where fcdaemon.DaemonMaxNumberOfInstances > 0, 
    and each of the processes in the DaemonRunningProcesses do the following:
?	Create a record in the output table tDaemonStatusInfo.
?	Fill in the current daemon status in the database (fcDaemon.DaemonStatus).
?	Check whether the process is still active on the server.  
    If the daemon is indicated to run on a different physical server (the ?DaemonAppServerConnection? is specified), 
    this needs to be done via a call to another appserver.  
    If the process id is still in the process table of the server, then indicate the true status as ?true?, else ?false?.
