That won't make any difference; it's not the variable *names* that
are the problem, it's the *values*. $ENV{REMOTE_ADDR} should have
a value. $ENV{REMOTE_HOST} may or may not. What web server are you

No, you're OK using vars inside qq(). Just make sure the variables
are spelled right and use the 'no warnings' to get rid of the
warning messages.
