I just added a patch to https://github.com/pkoning2/decstuff, in patches/shut.cmd, which cures a problem in RSTS V10.1 that seems to come and go with no clear pattern. The failure is a crash, sometimes a halt, during system shutdown. The cause was a write to the wrong location when removing the DCL runtime system, because of a register not being set before that action.
The patch can be installed with ONLPAT; it takes effect immediately (because it
patches a non-resident overlay).
