Dear All,
Does anybody know how I can set a WINNT Environment Variable
from within PERL 5 for NT? I can get the listing using $ENV
but I do not appear to be able to change it.

Alternatively, does anybody know how to raise an ERRORLEVEL
that can be tested from a batch file.

Regards,
    Anthony Farrow

If this is like the unix version of %ENV, then you can only change
it for the _current_ process and any _child_ processes. It does
not permanently modify the %ENV.
