%                Immediate macro                              Macro Directive

  % macro_body_line

    The % immediate macro directive treats a line of text as if it's a
    macro body. The dummy argument names used for the macro body include
    all of the text macros defined at that time.

    macro_body_line represents the macro body to use for the immediate
    macro expansion.

    Example:    mdl_size EQU <LARGE>
                mdl_language EQU <WINDOWS PASCAL>

                % MODEL mdl_size, mdl_language  ;MODEL LARGE, WINDOWS PASCAL
