The address in this vector is also copied into locations 0Eh through 11h of the program segment prefix (PSP) when a program is loaded but before it begins executing, and is restored from the PSP (in case it was modified by the application) as part of MS-DOS's termination handling. This interrupt should never be issued directly. -♦-
