yeah... with
START /m finsert ...
you can do batch-inderting in background
(well, your taskbar would be covered wirh all those ugly minimized windows...
but, well, bad OS...)

i don't know hos DOS-MM works exactly, but methinks the number of TSRs is
limited by memory-size only....

DOS (that ones i know) doesn't do any kind of task-managment.
TSRs make a interrupt-vector point to a part of them (sometimes, this
part even CALLs the original destination of the vector, too), and then call
the terminate-and-stay-resident-DOS-function. so the part of them is
executed every time this interrupt is triggered. anti-virus stuff that
checks each file you execute for viruses, e.g. will most probably catch
the DOS function call (INT 21, afaik) and checks files the user want to execute.
other stuff, like screensavers, catch IRQ0, the system timer, so they are
invoked regulary, and can check if it's time to black the screen.

hmmm, mouse is a dimple TSR... bit ANSI is somehow plugged in dos....
don't ask me how... i once tried to find out and failed (hey, actualy
microsoft.com should contain info 'bout dos)
