in reply to How do I...Conditional hash value

First off, beware the "= vs. eq vs. ==" bug. Remember that = does an assignment, == compares numeric values, and eq compares string values. Having said that, what you're probably looking for is the ternary ?: operator (documented in perlop). I'd write what you're looking for like this:

my %required; $required{path} = ($ENV{HTTP_HOST} eq '') ? 'g:/websites/' : 'd:/users/http/html/';

Then again, if you have several keys to set, you're probably better off doing:

my %required; if ($ENV{HTTP_HOST} eq '') { # We now know which # platform we're on... $required{path} = 'g:/websites/'; $required{someotherkey} = 'some other string'; } else { $required{path} = 'd:/users/http/html/'; $required{someotherkey} = 'some different string'; }
