NAME
       MacroCmd - a command that composes other commands

SYNOPSIS
       #include <Unidraw/Commands/macro.h>

DESCRIPTION
       MacroCmd composes other commands in a linear fashion.  Executing a MacroCmd is equivalent to executing its children in preorder.

PUBLIC OPERATIONS
       MacroCmd(ControlInfo*)
       MacroCmd(
	   Editor* = nil,
	   Command* first = nil, Command* second = nil,
	   Command* third = nil, Command* fourth = nil
       )
	      Construct a MacroCmd instance, optionally supplying up to four of its child commands.

       virtual void Execute()
       virtual void Unexecute()
       virtual boolean Reversible()
	      Execute  simply executes each child, from first to last.	Unexecute calls Unexecute on each child, from last to first.  The MacroCmd
	      is reversible if any of its children are.

       virtual void SetEditor(Editor*)
	      SetEditor calls SetEditor on each child with the given argument.

       Command* GetCommand(Iterator)
       void SetCommand(Command*, Iterator&)
	      GetCommand returns the child Command to which an iterator points.  SetCommand initializes the iterator  to  point  to  a	particular
	      child Command; it initializes the iterator to point to a nil instance if the given Command is not a child.

       void Append(
	   Command*, Command* = nil, Command* = nil, Command* = nil
       )

       void Prepend(
	   Command*, Command* = nil, Command* = nil, Command* = nil
       )

       void InsertAfter(Iterator, Command*)
       void InsertBefore(Iterator, Command*)
       void Remove(Command*)
       void Remove(Iterator&)
	      Operations  that	modify the MacroCmd's list of children. Append and Prepend add up to four Commands to the end and the beginning of
	      the list, respectively.  InsertAfter and InsertBefore insert a Command after and before the Command  pointed  to	by  the  iterator,
	      respectively.   The  Remove  operations remove a child from the list without deleting it.  You can remove a child by referring to it
	      explicitly or by specifying an iterator.	If an iterator is supplied, the Remove operation should advance it to point to the follow-
	      ing child as a side effect.

PROTECTED OPERATIONS
       Command* Cmd(UList*)
       UList* Elem(Iterator)
	      Convenience functions for extracting a Command from a UList element a UList from an iterator, respectively.
