SPECIFY Obsolete

        SEPCIFY [...] /FOR Buffer

      This syntax is replaced by the optional  first  argument  to  specify  the
    Buffer name.

    This OBSOLETE syntax behaviour was:
    If  present  the /FOR option indicates which buffer or Image variable should
    be affected. If no /FOR option is given, all relevant available buffers  are
    affected (CLEAN, DIRTY, UV, etc...).
