I suggest that the calling program pass to the called program (as a
command line argument, or an environment setting) a far pointer to a
global variable.  The called program can than put a pointer to
itself (or its PSP or whatever you meant by the above) in the
location indicated by said pointer.  When it returns control to the
caller, the caller can find out where the called program was.
