Question:
What is the definitive Microsoft reference that describes "the rules"
for creating a TSR?
Response:
Since the DOS environment is so loosely structured, there are no hard
and fast rules that guarantee that a TSR will work correctly with any
application. The best source for this information is the "MS-DOS
Encyclopedia" (published by Microsoft Press). This excellent reference
contains a 37-page chapter on TSRs, and other related information on
exception handlers and hardware-interrupt service routines. If you
take care to write your TSR in the manner described in this reference,
you will minimize interactions and other problems.
