	I've written a program to directly modify the parent environment
space in DOS (COMMAND.COM's evironment), but I need to know more about it.

	Is there a size field that keeps track of the total size of the
environment, or is size marked only by the NUL-NUL pair at the end or the
string space?  I've written the program to truncate certain entries, and I
need to know if I should move the rest of the environment up, or if there
is a size field I also must modify.

	If you have information (DOS tech. ref. manual, for instance),
*please* respond (preferably by e-mail).  Thanks!
