It is possible to mark code or data as "resident" meaning it will remain in
memory permanently.  This is required for code that would execute in an
interrupt context for example, including all I/O drivers and much of the MPE
kernel.

There's no other "TSR" equivalent feature that I can think of, mostly
because there's really no place to put such a thing.

Nothing other than its being (generally) unsuitable for Real Time
programming :-)

IIRC, MPE was originally designed to support on-line, batch *and* real time
processing, but the real time stuff got dropped before the first real
customer version of the OS.

Generally if you really want MPE to do something there's probably a way to
get it to do it, though perhaps not in a way that's easily describable using
terms from other operating systems.

The :ALLOCATE command permanently "loads" (resolves load-time external
references) a CM program but does *not* in any way reserve memory for it.
