There is nothing which says that a TSR must be made a .COM file. In fact,
some code simply cannot be made into a .COM file (any code which the linker
is required to generate fixups on will not be able to be made a .COM)

Making an EXE TSR is a little more complicated, in that you need to know
where the code segment is relative to the PSP, and how  many paragraphs the 
TSR is going to take when you make the DOS call. I don't think the INT 27H
TSR interrupt will work for this, but rather DOS function 31H will do the TSR
in this "style'

Hope this helps ....
