+---------------
| A recent posting discussed details of the INT21 4BH load-overlay subcode.
+---------------

It's documented in the ITT XTRA DOS manual.

I have heard that 4BH's subfunction 2 is reserved because the intended func-
tion is the equivalent of fork() and exec() with no wait() under UN*X; in
other words, to start a background process.
