For both Al and Pascal ...

Pascal is quite right.  I've used his Win32POSIX packages successfully
on Windows systems (i.e., 95/98/NT).  I've also used them with ObjectAda
7.1.2a at work and with GNAT 3.11p at home, and have never experienced a
problem.  The POSIX package bodies show how the Win32 API can be used to
implement the POSIX functionality and thus are quite instructive for
those learning the Win32 API.  A great example is demo6 in the
aforementioned Win32POSIX binding.  Is uses the package
POSIX.POSIX_Process_Environment and demonstrates its many services for
dealing with environment variables and strings.

So Al, although the Win32 API is popular, I would suggest that you tuck
my previous example code into a nice bit bucket somewhere and follow the
example shown in the demo6 program.  Pascal rightly points out that
POSIX is a much more portable means of dealing with environment
variables, and other operating system services as well.
