XM is eXtended Monitor, SJ is Single Job and there was also RT11FB for
foreground/background which let you have not-quite-multitasking on a single
user system. The reasons for us using XM over FB or SJ have been lost in the
mists of time - we used CTS300 over the top of the OS so it didn't matter
whether it was true single user or not. Bits of me think XM had the extra
functionality we needed for a multi-user runtime system but.....

When I have a nose through my disks it should refresh the old memory
somewhat :)
