canAcceptCommand()

Description	Determines whether the menu item should be active or dimmed.
Arguments	{arg1}, {arg2},...{argN}}
	If the arguments attribute is defined for a menuitem tag, the value of that attribute is passed to the canAcceptCommand() function (and to the isCommandChecked(), receiveArguments(), and setMenuText() functions) as one or more arguments. The arguments attribute is useful for distinguishing between two menu items that call the same menu command.
Returns	A Boolean value indicating whether the item should be enabled.
