carries - syntax: carries(CH,"item") 

Tests whether or not the character is carrying an item. The "item" variable can be either keywords or an object key. Usually it is better to use the object key so you can be sure the correct item is targeted. Using the keyword 'red sword' would mean any item with keywords 'red sword' would pass the test.
