IF2              Assemble If Pass 2                            MASM Directive

  IF2
  statements
  [ELSE
  statements]
  ENDIF

    Initiates a conditional block, causing assembly of the statements up
    to the optional ELSE directive, provided the current assembly pass is
    Pass 2.

       Notes:     IF2 tests only for the current assembly pass, and
                  therefore takes no expression argument.
