Well, if you want the value of a single environment variable, you can
always use the getenv() call.  If however you want to access the entire
list of environment variables (or you don't know the name of one in
particular and wish to search the entire list), then you can access the
global variables 'environ' (in Borland C -- I assume Microsoft C has
something similar).  Environ is of this type:

    extern char *environ[];

and is declared in <dos.h>.  Environ is a NULL terminated array of
string pointers.  Each string is of the form:

    VAR=value

Hope that helps.
