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).
