%OUT             Display Text during Assembly                       Directive

  %OUT      text

    Causes the assembler to echo text to the screen during assembly. The
    text is displayed when the %OUT directive is encountered in the source
    code, thus the status of a long assembly can be displayed.

       Notes:     The %OUT directive will be interpreted twice, once for
                  each pass.  Use IF1 and IF2 to display messages
                  according to which pass is executing.
