System Automation can use SYSCONS with the Processor Operations (ProcOps)
functionality. I take advantage of that, having SYSCONS activated in PD
mode 24/7, but issue VARY CN(*),ROUT=NONE on that console once the system
is fully up (the MONITOR JOBNAMES/SESS/STATUS console attribute is honored
regardless of ROUT settings) . At system shutdown time, another VARY
CN(*),ROUT=(1,2,10) is issued for monitoring progress and "external"
automation when the time comes. D C,CN=<SysCons name> may show some
undesirable routing codes or DEL attributes included in the CONSOLxx
"DEVNUM(SYSCONS)" definitions.
