This service gets or sets information about APPEND. In particular, you
can determine whether or not APPEND is active, and if so, what version
number is in use. You can also query or set a number of switches (/PATH,
/E and /X).
Notes: In Subservice 11h, a process system state flag is
set. On the next INT 21h function call 3DH, 43H, or 6CH
that APPEND processes, it returns the name it finds to
the application filename buffer.
