// macro
//
// Special Note The macro keyword is retained in Director 3.0 to maintain compatibility
// with scripts developed under Version 2.0. When writing new scripts, or editing old
// scripts, you should use handlers instead of macros. (Handlers are defined with the on keyword.)
//
// Syntax:
//
// -- [comment]
// macro macroName [argument1] [, argument2]
// [, argument3]
// [statement1]
// [statement2]
//
// Keyword. Defines a macro. A macro is a multiple-line script defined
// in the Text window. Macros can accept arguments (inputs) and
// optionally return a result. Macros can call other macros and can be
// called from any other script or factory.
//
// The first line of a castmember in the Text window that contains a macro must be
// a comment (--). You can define more than one macro in a given text castmember.
// The macro definition ends where the next macro (or factory) begins.
