[Macintosh Technical Notes - #126: Sublaunching: playing the Shell game]

NOTE: Macintosh Technical Support takes the view that this  is  a
feature  which  is  best  left  out for compatibility (and other)
reasons, but we want to make sure  that  when  it  is  absolutely
necessary to implement it, it is done in the safest way.

Herein is a means to launch an application from your program  and
have  it  return  to  you  as  though you were a "shell" like the
Finder.  There are unresolved issues, though (and some  downright
problems), so please read the cautionary notes which follow.

Changes since 5/87 include advising you to set both high bits  of
LaunchFlags  for  future  compatibility.   Throwing  away working
directories that you created is no longer  recommended.   If  you
are  opening  working  directories, you should make sure to check
for errors (tMWDOErr = -121) after calling PBOpenWD.
