*     TFXD PROVIDES A FORTRAN-CALLABLE CONVERSION FROM
*     DOUBLE-PRECISION (64-BIT) FLOATING-POINT TO DOUBLE
*     INTEGER.
* 
*     CALLING SEQUENCE: 
* 
*                   FTN,L,Y 
*                     . 
*                     . 
*                   DOUBLE PRECISION DX 
*                     . 
*                     . 
*                   Y = TFXD(DX)
* 
*     WHERE Y IS DECLARED REAL BUT CONTAINS A DOUBLE
*     INTEGER VALUE.  THE RESULT IS TRUNCATED.
* 
*     OVERFLOW IS SET ONLY IF THE ARGUMENT IS OUTSIDE THE RANGE 
*     [-2**31,+2**31), AND IS TESTABLE BY THE ROUTINE "OFL".
