%ENV may also be localized:

{
    local %ENV;        # Old %ENV saved away in case you need it
                       # outside this scope.
    %ENV = ( ...... ); # Create your own custom %ENV.
    # Most of your script here...
}
# Here, %ENV will be restored to the original, in case you need
# it for something else.

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
