     Removes an argument from future consideration as a special data item.
     Takes 1 or more arguments...
     All: The argument to remove from the preceding argument list.
===Comments===
Using this is required if you intend to cycle through a list of non-recurring arguments in an event based on conditionals featuring arguments, like [[every-time-argument]] and [[when-argument]]. Otherwise, an argument remains valid even after it has been used once.

In earlier versions of FreeSpace Open, the default value used to be <any data>. In current versions, it's <argument>.
