	FileListOp ()
	Constructor for the File List Operation.
void	Do (OpDescriptor *)
	Attempts to load a file that was in the Recent file list.
Static Public Member Functions
static BOOL	Init ()
	Initialises the FileList Operation. It tries to create several OpDescriptors that will be associated with each of the menu items on the recent file list. They will all invoke this operation and the operation will try to work out which one invoked it.
static OpState	GetState (String_256 , OpDescriptor )
	Descides if this operation shold be available or not.
Static Public Attributes
static INT32	MaxFileListSize = 4
	Describes how many files will be displayed in the Recent file list.
