  Actually, the info is recorded at the end of a program's copy of the
DOS environemnt in DOS versions 3.0 and above.  Environment variables
are stored as null terminated strings, there's an extra null after the
last environment variable, and then the name of the currently
executing program follows.  You find the segment location of your copy
of the environment at a specified place in the PSP, but I don't think
the name of the program is there.
