CLEAR_INTERLOCKED

 The CLEAR_INTERLOCKED function assigns the value  FALSE  to  the
 parameter   and  returns  the  original  Boolean  value  of  the
 parameter.


 Syntax:

    CLEAR_INTERLOCKED( b )


 The variable 'b' must  be  a  variable  of  type  Boolean.   The
 variable  does  not  have  to be aligned; therefore, it can be a
 field of a packed record.
