MACRO            Initiate Macro Definition                          Directive

  name      MACRO     [dummyparameter,,,]
  statements
  ENDM

    Initiates the definition of a macro, containing the name and statements
    within the macro. In TASM Ideal mode, the name of the macro comes after
    the keyword MACRO, like this: MACRO name arguments.

       Notes:     The name must be valid and unique.

                  Any number of dummy parameters may be declared, provided
                  they all fit on one line. These dummy parameters act as
                  place holders; on expansion they are replaced by actual
                  parameters passed in the macro call.

                  Macros may be nested to any depth, may call other
                  macros, and may call themselves. They may also be
                  redefined.

                  Macros generate code when they are called, not when
                  defined.  All addresses generated are relative to the
                  position of where the macro is called, not where it is
                  defined.

                  Be careful in using the word MACRO in TITLE, SUBTTL, and
                  NAME directives.  Since MACRO will override these
                  directives, using MACRO with these directives could
                  cause the user to have macros called TITLE, SUBTTL, and
                  NAME.
